| 1. A process for the preparation of a benzylated amine with the co-production of by-product hydrogen halide, by the reaction of an amine selected from the group consisting of methamphetamine and propylhexedrine with a benzyl halide in a reaction vessel wherein said amine is in molar excess with respect to the benzyl halide and such excess reacts with by-product hydrogen halide to produce an amine halide. |
