Procedure
A 389 mg portion of the thus obtained (1R)-1-(1-naphthyl)-N-{[(3S,4S)-4-phenyl-1-(trifluoroacetyl)pyrrolidin-3-yl]methyl}ethanamine was dissolved in 5 ml of ethyl acetate and treated with a 4 M hydrogen chloride/ethyl acetate solution. The reaction solution was diluted with hexane, and the thus precipitated solid was recrystallized from ethyl acetate and hexane to obtain 268 mg of (1R)-1-(1-naphthyl)-N-{[(3S,4S)-4-phenyl-1-(trifluoroacetyl)pyrrolidin-3-yl]methyl}ethanamine hydrochloride as colorless crystals.
