Here it is again. Some improvements to the PPA extraction process were surmised through empirical testing. A mixed solvent system of ethanol and water is now called for, and results in 100% extraction efficiency with super-speedy filtering. This works only for the *non-time-release* tablets,. The time release ones are a different story, I am told, and require much more processing time and crap to deal with.
Some other changes to help clarify the street nomenclature has also been added due to the e-mail I have received. Enjoy, and remember, if you want this to be a *real* FAQ, you guys have to send me more comments.
The 4-Methylaminorex pseudo-FAQ (beta)
Due to strangely increased demand for 4-Methylaminorex "recipes" that I have received by mail, I decided to compile a short document with the cognate preparation of this interesting compound. This may become a full-fledged FAQ in the future, depending on user response and outside input donated where this will undoubtedly be deficient.
Q1. What is Ice?
A1. Ice is a norepinephrine potentiator (neuromodulator class). It has a characteristic look and feel, like white opaque ice, hence the name. Ice is currently a Schedule I drug as designated by the DEA (Drug Enforcement Agency) which means it is felt to have NO medical use whatsoever. It was originally researched for appetite suppressant ability, but never pursued, probably because it's too much fun. Ice is also synonymous with "U4Euh".
Q2. Can Ice/U4Euh be made from amphetamine/methamphetamine?
A2. It is *technically* possible, but requires some backwards motions to get back to a sec. alcohol. At least one individual, in a personal communication to me, indicated that "they knew of someone who could convert crank [methamphetamine] into ice by washing it with something". This is not possible and more than likely is just a street name for clean crank (meth).
Q3. What kind of chemical is it?
A3. In drug parlance, which is notoriously Non-IUPAC compliant, Ice is synonymous with "Euphoria" (U4Euh), 4-Methylaminorex, or, chemically speaking: dl-cis-2-amino-4-methyl-5-phenyl-2-oxazoline. This is a tongue twister of a name, so I will explain and illustrate it with a cheap floozie of an ascii drawing.
//\ // \____ _____ ____CH3 | || | | | || | | \\ / O N \\/ \ // \// | N / \ H H
The numbering starts at the heterocyclic Oxygen and goes counter-clockwise. So the amine is at the 2 position, the methyl is at the 4 position, a phenyl ring is tacked on at the 5 position. Also, the 2-oxazoline part is often merely called oxazoline, as the double bond to the heterocyclic Nitrogen is implied.
It is interesting to note that all of the stereoisomers of 4-MAR are centrally active  (ie - it is not stereospecific in action).
Cognate Preparation of 4-Methylaminorex
Extraction of Phenylpropanolamine from OTC preparations
Forming the Oxazoline Ring
The ideal ratio of all the reagents is as follows :
The Sodium Acetate may be prepared by carefully adding an equinormal amount of Sodium Hydroxide to glacial Acetic Acid and drying the resultant salt at 120C for 15 minutes.
The preparation of Cyanogen Bromide is covered in another document of mine.
This compound should only be prepared in an area of *adequate* ventillation. A full covering fume hood is ideal (geez - make one, I did) or outside with the wind blowing away from you. Cyanogen Bromide acts on cytochrome oxidase just like any other cyanide and can kill you quite effectively and quickly. Also, it has been known to decompose spontaneously when impure.
