Procedure

To a solution of 888 mg of 4-(methoxycarbonyl)phenyl 4-(4-fluorophenyl)-3-({[(1R)-1-(1-naphthyl)ethyl]amino}methyl)piperidine-1-carboxylate in 9 mL of dichloromethane were added 0.7 mL of triethylamine and 868 mg of di-tert-butyl carbonate, followed by stirring at room temperature for 37 hours. The reaction mixture was concentrated under reduced pressure, and the residue was purified by silica gel chromatography (hexane-ethyl acetate) to obtain 503 mg of 4-(methoxycarbonyl)phenyl 3-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-4-(4-fluorophenyl)piperidine-1-carboxylate as a pale yellow foamy substance.
