It can also be done by reacting with formaldehyde to form an imine, and then reducing it. If you can find a rhodium.ws archive or mirror, check out
"Synthesis of Phenylpropanolamine and (Pseudo)Ephedrine ".

Re:methylation of the amine group
Best if you check while viewing rhodium's archives , the methylation of amphetamine, in which it converts it to methamphetamine the chemistry is
the same for SWIM particular application ..............solo
