To a solution of 175 mg of the crude product of (1R)-1-(1-naphthyl)-N-[(4-phenylpiperidin-3-yl)methyl]ethaneamine and 142 μL of triethylamine in 3.5 mL of THF was added 120 mg of methyl 4-[(chlorocarbonyl)oxy]benzoate (Fluka) under ice-cooling. After stirring at room temperature for 30 minutes, the reaction mixture was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (hexane-ethyl acetate) to obtain 237 mg of 4-(methoxycarbonyl)phenyl 3-({[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-4-phenylpiperidine-1-carboxylate.
