N-Methoxy-MDA · 3,4-Methylenedioxy-N-methyoxyamphetamine
SYNTHESIS: To a solution of 20.9 g methoxyamine hydrochloride in 75 mL MeOH (a strongly acidic solution) there was added 4.45 g 3,4-methylenedioxyphenylacetone (see under 2O, acidified with 10 mL HCl, and extraction with 3×100 mL CH2Cl2 removed almost all the color. The aqueous phase was made basic with 25% NaOH, and extracted with 4×100 mL CH2Cl2. Evaporation of the solvent from these extracts yielded 1.8 g of a pale yellow oil which, on distillation at 90–95 °C at 0.5 mm/Hg, gave a 1.6 g fraction of an absolutely white, viscous, clear oil. This was dissolved in 8 mL IPA and neutralized with concentrated HCl. The product was an exceptionally weak base, and appropriate end points must be respected on the external pH paper (yellow to red, rather than purple to orange). Anhydrous Et2O was added to the point of turbidity, and as soon as crystallization had actually started, more Et2O was added with stirring, for a net total of 200 mL. After a couple of h standing, the fine white crystalline 3,4-methylenedioxy-N-methoxyamphetamine hydrochloride (MDMEO) was removed by filtration, Et2O washed, and air dried to constant weight. There was obtained 1.7 g of a product with a mp of 143–146 °C. The proton NMR was excellent with the N-methoxyl group a sharp singlet at 4.06 ppm. Anal. (C11H16ClNO3) N.
DOSAGE: greater than 180 mgs.
EXTENSIONS AND COMMENTARY: Why the interest in the N-methoxy analogue of
The ultimate reason for making MDMEO was, of course, that it could be made. That reason is totally sufficient all by itself.
About PiHKAL · info
This version of Book II of PiHKAL is based on the Erowid online version, originally transcribed by Simson Garfinkle and converted into HTML by Lamont Granquist. I drew also on “Tyrone Slothrop’s” (Unfinished) Review of PIHKAL to enumerate the many analogues mentioned in PiHKAL but not described at length. Many, many others have since been added.
I have tried here to expunge any artifacts introduced by the earlier transcriptions and restore the typographic niceties found in the printed edition. I’ve also made minor changes to some chemical names in line with current nomenclature practice. Typically the change is little more than expanding a prefix or setting it in italics. The history page has further details.
“At the present time, restrictive laws are in force in the United States and it is very difficult for researchers to abide by the regulations which govern efforts to obtain legal approval to do work with these compounds in human beings.“No one who is lacking legal authorization should attempt the synthesis of any of the compounds described in these files, with the intent to give them to man. To do so is to risk legal action which might lead to the tragic ruination of a life. It should also be noted that any person anywhere who experiments on himself, or on another human being, with any of the drugs described herein, without being familiar with that drug’s action and aware of the physical and/or mental disturbance or harm it might cause, is acting irresponsibly and immorally, whether or not he is doing so within the bounds of the law.”

PiHKAL is the extraordinary record of the authors’ years exploring the chemistry and transformational power of phenethylamines. This book belongs in the library of anyone seeking a rational, enlightened and candid perspective on psychedelic drugs.
Though Sasha and Ann have put Book II of PiHKAL in the public domain, available to anyone, I strongly encourage you to buy a copy. We owe them — and there’s still nothing quite like holding a real book in your hands.
