Abstract
An optically active 1-(fluoro-, trifluoromethyl- or trifluoromethoxy-substituted phenyl)alkylamine N-monoalkyl derivative represented by the formula 4 is produced by a process including (a) reacting an optically active secondary amine, represented by the formula 1, with an alkylation agent R—X, in the presence of a base, thereby converting the secondary amine into an optically active tertiary amine represented by the formula 3; and (b) subjecting the tertiary amine to a hydrogenolysis, thereby producing the N-monoalkyl derivative,
