A quick search of several neighborhoods of the United States revealed that while pseudoephedrine is difficult to obtain, N-methylamphetamine can be procured at almost any time on short notice and in quantities sufficient for synthesis of useful amounts of the desired material. Moreover, according to government maintained statistics, N-methylmphetamine is becoming an increasingly attractive starting material for pseudoephedrine, as the availability of N-methylmphetamine has remained high while prices have dropped and purity has increased [2]. We present here a convenient series of transformations using reagents which can be found in most well stocked organic chemistry laboratories to produce psuedoephedrine from N-methylamphetamine.
Edit 2023-10-03 to update the link, used to point to heterodoxy.cc/meowdocs/pseudo/pseudosynth.pdf but that's been hijacked by spammers.
