PROCESS FOR THE PREPARATION OF AMINE DERIVATIVES

摘要

A process for safely preparing methylamine derivatives by reacting an amine with trimethyl phosphite and an oxidizing agent such as N-halogenoamide; and novel {dimethyl}{N-[3-(4-methylphenyl)-8,9-dihydro-7H-benzocycloheptenecarbonyl]-4-aminobenzyl}{4-tetrahydropyranyl}ammonium compounds.
