#81 Flea; n-hydroxy-n-methyl-3,4-methylenedioxyamphetamine

SYNTHESIS: (from 3,4-methylenedioxyphenylacetone) A solution of 2.1 g N-methylhydroxylamine hydrochloride and 4.4 g 3,4-methylenedioxyphenylacetone in 5.5 mL MeOH was added to a suspension of 4.5 g NaHCO3 in 30 mL boiling MeOH. There was added about 5 mL H2O (which gave a clear solution) followed by another 50 mL H2O which produced a pale yellow color. To this solution of the unisolated nitrone there was added 1.7 g sodium cyanoborohydride, which generated a goodly amount of foaming. There was HCl added as needed to maintain the pH at about neutrality. The reaction appeared to have stopped after a day or two, so all was poured into 500 mL H2O, acidified with HCl, and washed with 2x75 mL CH2Cl2. The addition of base brought the pH >9, and this was then extracted with 3x75 mL CH2Cl2. Removal of the solvent from the pooled extracts gave a residue of 1.65 g of crude N-hydroxy-N-methyl-3,4-methylenedioxyamphetamine. Efforts to obtain solid seed samples of the salts with hydrochloric acid, perchloric acid, sulfuric acid, phosphoric acid, and with a number of organic acids, all failed. The salt formation from this free-base will be discussed below.

(from MDOH) A solution of 0.75 g crystalline free-base MDOH in a few mL MeOH was treated with a solution of 0.4 g sodium cyanoborohydride in 10 mL MeOH, and there was then added 2 mL of 35% formaldehyde. The stirred reaction mixture was kept at a neutral pH with the occasional addition of HCl. After several days (when additional acid was no longer required) the excess solvent was removed under vacuum, and the residue poured into dilute H2SO4. This was washed with 2x75 mL CH2Cl2 and then, following the addition of base, this was extracted with 3x75 mL CH2Cl2. Removal of the solvent from the pooled extracts gave a viscous oil residue of 0.53 g. The free-base product from these preparations was distilled at 110-120 deg C at 0.2 mm/Hg to give the N-hydroxy-N-methyl product as a white oil. An alternate methylation procedure used a solution of MDOH in a 4:1 MeOH/acetic acid solution containing formaldehyde which was reduced with sodium borohydride at dry ice temperatures. Its work-up is identical to that involving sodium cyanoborohydride.

The distilled product was dissolved in an equal volume of MeOH, and treated with a half-equivalent of oxalic acid dihydrate, dissolved in 10 volumes of MeOH. This combination gave the slow deposition of crystals of the full oxalate salt (one acid, two bases) as a white crystalline product. The mp of the crude salt was in the 130-150 deg C range, and after recrystallization from CH3CN, N-hydroxy-N-methyl-3,4-methylenedioxyamphetamine oxalate (FLEA) had a mp of 146-147 deg C.

DOSAGE: 100 - 160 mg.

DURATION: 4 - 8 h.

QUALITATIVE COMMENTS: (with 90 mg) The material tastes terrible, like grapefruit juice that has stayed in the can too long. There was no nausea, no feeling of difficulty in swallowing at any time during the day. I felt a dry mouth and was thirsty Q sipped water throughout the day. At the beginning of the experiment, there was a glimmer of the MDMA warmth, but later I felt separated and a bit isolated. I was just floating around, seeing the beauty of colors and objects in the house and outdoors and listening first to this conversation, then to that one. All senses seemed enhanced. I found the material pleasant. I was happy with the amount I took but would not be afraid to take more or to take a supplement. I found it similar to, but not the same as, MDMA.

(with 110 mg) We found this very similar to MDMA, but perhaps slightly slower. I plateau'd at 2:30 hours and had a very gradual descent. My friend had a marvelous and private 'cone of silence' that was to him unique to MDMA or to 2C-T-8. Teeth problems were minor, and the descent from the top of the experience showed less interactive, and more contemplative action, than with MDMA. Very similar to MDMA, but with its own character.

(with 110 mg) The onset was at about a half-hour. The come-on was more gradual and much easier than with MDMA, and it seemed to be more head than body oriented. I had about two hours of very complex and personal self-evaluation, and I am not at peace in putting all of it down here in writing. Overall I like it, and I would be interested to see if there's a difference in conjunction with MDMA. Thanks very much.

(with 110 mg + 35 mg) I saw my onset at 20 minutes, and it was subtle, and very pleasant, and had a mild amphetamine-like elevation for me (body lightness, cognitive functions seemed clear and clean, heightened visual awareness and with some enhancement of color). It seemed as if I were on the fringe of LSD-like visual changes, but that never materialized. The affect was very good, communicative, friendly, accepting, but without the profound emotional bonding of MDMA. The following day felt very much like a post-LSD day; we felt great. The body was light, energy good, emotions high, several insights throughout the day, interactions clear and open Q a magnificent gift of a day. I started a menstrual period the day of the experience and it lasted 6 to 7 days; all of this was a couple of weeks early. I have a very favorable impression of FLEA although the body penalty seems high.

EXTENSIONS AND COMMENTARY: Most people who were involved with the evaluation of FLEA quite logically compared it with MDMA, as it was presented as being a very close analogue which might share some of the latter's properties. And to a large measure, the comparison was favorable. The dosages are almost identical, the chronological course of action is almost identical, and there are distinct similarities in the effects that are produced. If there is a consensus of similarities and differences it would be that it is not quite as enabling in allowing a closeness to be established with others. And perhaps there is more of a move towards introspection. And perhaps a slightly increased degree of discoordination in the thought processes. But also, part of this same consensus was that, were MDMA unknown, this material would have played its role completely.

And from the scientific point of view, it lends more weight to a hypothesis that just might be a tremendous research tool in pharmacology. I first observed the intimate connection between an amine and a hydroxylamine with the discovery that N-hydroxy-MDA (MDOH) was equipotent and of virtually identical activity to the non-hydroxylated counterpart (MDA). And I have speculated in the recipe for MDOH about the possible biological interconversions of these kinds of compounds. And here, the simple addition of a hydroxyl group to the amine nitrogen atom of MDMA produces a new drug that is in most of its properties identical to MDMA. The concept has been extended to 2C-T-2, 2C-T-7, and 2C-T-17, where each of these three active compounds was structurally modified in exactly this way, by the addition of a hydroxyl group to the amine nitrogen atom. The results, HOT-2, HOT-7 and HOT-17 were themselves all active, and compared very closely with their non-hydroxylated prototypes.

Just how general might this concept be, that an N-hydroxyl analog of an active amine shall be of similar action and duration as the parent drug? What if it really were a generality! What havoc it would wreak in the pharmaceutical industry! If I could patent the concept, then I would be able to make parallel best sellers to all of the primary and secondary amines out there in the industry. Perhaps 90% of all the commercially available drugs that are concerned with the human mental state are amines. And a goodly number of these are primary or secondary amines. And each and every one of these could be converted to its N-hydroxyl analogue, effectively by-passing the patent protection that the originating corporation so carefully crafted. An example, just for fun. A run-away best seller right now is an antidepressant called fluoxetine, with the trade name Prozac. I will make a small wager that if I were to synthesize and taste N-hydroxy-N-methyl-3-phenyl-3-((a,a,a-trifluoro-p-tolyl)oxy)propylamine, I would find it to be an active antidepressant. Remember, Mr. Eli Lilly and Company; you read about it first, right here!

Of course, I was asked, why call it FLEA? The origin was in a classic bit of poetry. A commonly used code name for MDMA was ADAM, and I had tried making several modest modifications of the MDMA structure in the search for another compound that would maintain its particular music without the annoying tooth-grinding and occasional nystagmus, or eye-wiggle, that some users have mentioned. One of these was the 6-methyl homologue which was, with some perverse logic, called MADAM. And, following this pattern, the 6-fluoroanalogue was to be FLADAM. So, with the N-hydroxy analogue, what about HADAM? Which brought to mind the classic description of Adam's earliest complaint, an infestation of fleas. The poem was short and direct. "Adam had 'em." So, in place of HAD 'EM, the term FLEA jumped into being.

#82 G-3; 2,5-DIMETHOXY-3,4-(TRIMETHYLENE)AMPHETAMINE;

5-(2-AMINOPROPYL)-4,7-DIMETHOXYINDANE

SYNTHESIS: A solution of 3.7 g of 2,5-dimethoxy-3,4-(trimethylene)benzaldehyde (see preparation under 2C-G-3) in 15 mL nitroethane was treated with 0.7 g anhydrous ammonium acetate and heated on the steam bath for 2.5 h. The excess solvent was removed under vacuum leaving some 5 mL of a deep orange-red oil which on cooling, spontaneously crystallized. This was finely ground under 10 mL MeOH, filtered, washed sparingly with MeOH, and air dried to give 3.6 g of orange crystals with a strong smell of old acetamide. The mp was 92-93 deg C. All was recrystallized from 30 mL boiling MeOH to give, after filtering and drying, 2.9 g of 1-(2,5-dimethoxy-3,4-(trimethylene)phenyl)-2-nitropropene as yellow crystals with a mp of 93-94 deg C. Anal. (C14H17NO4) C,H,N.

Fifty milliliters of 1 M LAH in THF was placed in an inert atmosphere, well stirred, and cooled to 0 deg C with an external ice-bath. There was added, dropwise, 1.35 mL of 100% H2SO4 at a rate slow enough to minimize charring. There was then added, dropwise, 2.8 g 1-(2,5-dimethoxy-3,4-(trimethylene)phenyl)-2-nitropropene in 15 mL THF. At the end of the addition, the stirring was continued for an additional 0.5 h, and then the reaction mixture was held at reflux on the steam bath for another 0.5 h. After cooling again to ice-bath temperature, the excess hydride was destroyed with the addition of 11 mL IPA, followed by 5.5 mL 5% NaOH which converted the inorganic mass through a cottage cheese stage into a loose, filterable texture. The solids were removed by filtration, washed with additional THF, and the combined filtrates and washes stripped of solvent under vacuum. There was obtained 2.51 g of a white oil that was distilled at 115-135 deg C at 0.2 mm/Hg to give 1.83 g of a clear colorless oil. This was dissolved in 8 mL IPA, neutralized with 28 drops of concentrated HCl, and diluted with 140 mL anhydrous Et2O. In about 0.5 h there started a slow snowfall of fine fluffy white crystals which was allowed to continue until no additional crystals appeared. After filtering, Et2O washing and air drying, there was obtained 1.81 g of 2,5-dimethoxy-3,4-(trimethylene)amphetamine hydrochloride (G-3) with a mp of 157-159 deg C. Anal. (C14H22ClNO2) C,H.

DOSAGE: 12 - 18 mg.

DURATION: 8 - 12 h.

QUALITATIVE COMMENTS: (with 12 mg) There was a warmth, a mellowness, as things developed. No body disturbance at all, but then there were no visuals either which, for me on this particular occasion, was disappointing. The day was consumed in reading, and I identified completely with the character of my fictional hero. It was a different form of fantasy. I think I prefer music as a structural basis for fantasy.

(with 18 mg) I am at a plus three, but I am not at all sure of why it is a plus three. With my eyes closed, there are puffy clouds, but no drama at all. Music was not exciting. There could well have been easy eroticism, but there was no push in that direction. No great amount of appetite. Not much of anything, and still a plus three. Simply lying still and surveying the body rather than the visual scene gave some suggestions of neurological sensitivity, but with getting up and moving about and doing things, all was fine. The next morning I was perhaps moving a bit more slowly than usual. I am not sure that there would be reward in going higher.

EXTENSIONS AND COMMENTARY: In a comparison between the 2-carbon compound (2C-G-3) and the 3-carbon compound (G-3) the vote goes towards the phenethylamine (the 2-carbon compound). With the first member of this series (2C-G versus GANESHA) this was a stand-off, both as to quantitative effects (potency) and qualitative effects (nature of activity). Here, with the somewhat bulkier group located at the definitive 3,4-positions, the nod is to the shorter chain, for the first time ever. The potency differences are small, and maybe the amphetamine is still a bit more potent. But there are hints of discomfort with this latter compound that seem to be absent with the phenethylamine. The more highly substituted compounds (q.v.) more clearly define these differences.

#83 G-4; 2,5-DIMETHOXY-3,4-(TETRAMETHYLENE)AMPHETAMINE;

6-(2-AMINOPROPYL)-5,8-DIMETHOXYTETRALIN

SYNTHESIS: A solution of 1,4-dimethoxy-5,6,7,8-tetrahydro-beta-naphthaldehyde (see preparation under 2C-G-4) in 20 mL nitroethane was treated with 0.13 g anhydrous ammonium acetate and heated on the steam bath overnight. The volatiles were removed under vacuum and the residue, on cooling, spontaneously crystallized. This crude rust-colored product (1.98 g) was recrystallized from 15 mL boiling MeOH yielding, after filtering and air drying to constant weight, 1.33 g of 1-(2,5-dimethoxy-3,4-(tetramethylene)phenyl)-2-nitropropene as dull gold-colored crystals. The mp was 94-94.5 deg C. Anal. (C15H19NO4) C,H.

DOSAGE: unknown.

DURATION: unknown.

EXTENSIONS AND COMMENTARY: The discussion that appeared in the commentary section under 2C-G-4 applies here as well. The major struggles were in the preparation of the aldehyde itself. And although the final product has not yet been made, this last synthetic step should be, as Bobby Fischer once said in his analysis of a master's chess game following a blunder by his opponent, simply a matter of technique.

As with the phenethylamine counterpart, G-4 has a structure that lies intermediate between G-3 and G-5, both potent compounds. It is axiomatic that it too will be a potent thing, and all that now needs be done is to complete its synthesis and taste it.

#84 G-5; 3,6-DIMETHOXY-4-(2-AMINOPROPYL)BENZONORBORNANE

SYNTHESIS: A solution of 3.70 g 3,6-dimethoxy-4-formylbenzonorbornane (see under 2C-G-5 for its preparation) in 20 g nitroethane was treated with 0.88 g anhydrous ammonium acetate and held at steam bath temperature overnight. The excess solvent and reagent was removed under vacuum to yield a residual yellow oil. This was allowed to stand at ambient temperature for a period of time (about 3 years) by which time there was a spontaneous crystallization. The dull yellow crystals were removed by filtration and, after air drying, weighed 4.28 g. A small sample was recrystallized repeatedly from MeOH to provide a pale yellow analytical sample of 3,6-dimethoxy-4-(2-nitropropenyl)benzonorbornane with a mp of 90-91 deg C. Anal. (C16H19NO4) C,H.

A solution of LAH (50 mL of 1 M solution in THF) was cooled, under He, to 0 deg C with an external ice bath. With good stirring there was added 1.32 mL 100% H2SO4 dropwise, to minimize charring. This was followed by the addition of 4.1 g 3,6-dimethoxy-4-(2-nitropropenyl)benzonorbornane in 20 mL anhydrous THF over the course of 10 min. The reaction mixture was stirred and brought to room temperature over the course of 1 h. This was then brought to a gentle reflux on the steam bath for 0.5 h, and then all was cooled again to 0 deg C. The excess hydride was destroyed by the cautious addition of 10 mL IPA followed by 5 mL 5% NaOH and sufficient H2O to give a white granular character to the oxides. The reaction mixture was filtered, and the filter cake washed with THF. The filtrate was stripped of solvent under vacuum providing a pale amber oil that was distilled at 125-140 deg C at 0.2 mm/Hg to give 2.5 g of an almost white oil. This was dissolved in 10 mL IPA, neutralized with 25 drops of concentrated HCl, and then diluted with 140 mL anhydrous Et2O. There appeared, after about two minutes, white crystals of 3,6-dimethoxy-4-(2-aminopropyl)benzonorbornane hydrochloride (G-5) which, after filtration and air drying, weighed 2.47 g.

DOSAGE: 14 - 20 mg.

DURATION: 16 - 30 h.

QUALITATIVE COMMENTS: (with 15 mg) As part of the audience at the San Francisco conference, Angels, Aliens and Archtypes, I could simply listen and observe without having to participate. Each speaker stood in a cone of light that was beautifully bright and colorful, casting everything else on the stage into obscurity. Maybe angels really are illuminated from above, and the aliens lurk out of sight until it is their turn. Where does one look for the archetypes? A half of a cream cheese sandwich was all I could eat, and even at dinner that evening I was not hungry. Sleep that evening was difficult.

(with 20 mg) Very slow to come on, but then it was up there all of a sudden. There is an unexpected absence of visual activity despite being at a full +++. The mental activity is excellent, with easy writing and a positive flow of ideas. But an absence of the bells and whistles that are expected with a psychedelic in full bloom. There is a real drop by the 16th hour and the next day was free of effect except for occasional cat-naps.

(with 20 mg) The transition period, which usually lasts for most compounds for the first hour or two, with this seems to be much longer. This presages a long-acting material, as usually the slow-in slow-out rule applies. But there are exceptions. There is an indifference towards the erotic, but no separation at all from personal interactions and emotions. I believe in integration, not separation of all parts of ourselves, distrusting any drug states (particularly those that have the reputation of being strongly `cosmic') which divorce the consciousness from the body. And with this material there is no separation from feelings, only from my particular color language.

EXTENSIONS AND COMMENTARY: This is as potent as any of the three-carbon Ganesha compounds, but it somehow lacks a little something that would have made it a completely favorite winner. Perhaps it is the generally commented upon absence of visual and related sensory entertainment. There seems to be no bodily threat to discourage further exploration, but there simply was not the drive to explore it much. The comments concerning the enlargement of the ring system (mentioned under 2C-G-5) are equally valid here. The "shrubbery" that is the hallmark of the Ganesha family is, with G-5, about as bulky as has ever been put onto a centrally active molecule. The norbornane group has a one carbon bridge and a two carbon bridge sticking out of it at odd angles. The replacement of the one-carbon bridge with a second two-carbon bridge would make the compound G-6. It would be makeable, but is there really a driving reason to do so? There is a simplification intrinsic in this, in that G-5 actually has two centers of asymmetry (the a-carbon atom on the amphetamine chain, and the norbornyl area itself) and so it is really a mixture of two racemic diastereoisomers. G-6 would still be a racemate, but it would be only a single compound, as are all the other substituted amphetamine derivatives.

Someday I may try making G-6, but it's not a high priority right now.
