Cyclopropylmethyl-MDA · 3,4-Methylenedioxy-N-cyclopropylmethylamphetamine
SYNTHESIS: A solution of 9.4 g cyclopropylmethylamine hydrochloride in 30 mL MeOH was treated with 1.8 g 3,4-methylenedioxyphenylacetone (see under 2O, acidified with HCl, and washed with 2×100 mL CH2Cl2. The aqueous phase was made basic with 25% NaOH, and extracted with 3×150 mL CH2Cl2. Removal of the solvent from these extracts under vacuum yielded 2.8 g of a crude product which, on distillation at 90–100 °C at 0.1 mm/Hg, yielded 0.4 g of a clear white oil. This was dissolved in a small amount of IPA, neutralized with a few drops of concentrated HCl, and diluted with anhydrous Et2O to the point of turbidity. There was obtained a small yield of crystalline 3,4-methylenedioxy-N-cyclopropylmethylamphetamine hydrochloride (MDCPM) which was filtered off, Et2O washed and air dried. The mp was 218–220 °C, with extensive darkening just prior to melting. Anal. (C14H20ClNO2) N.
DOSAGE: greater than 10 mg.
EXTENSIONS AND COMMENTARY: The record of the tasting assay of this compound is pretty embarrassing. The highest level tried was 10 milligrams, which showed no hint of activity. But in light of the rather colorful activities of other cyclopropylmethyl things such as
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.
