실험 절차

A mixture of 191 mg of tert-butyl {[4-(2-fluorophenyl)piperidin-3-yl]methyl}[(1R)-1-(1-naphthyl)ethyl]carbamate, 118 mg of methyl 3,4,5-trifluorobenzoate, 114 mg of potassium carbonate, and 2.0 mL of THF-2.0 mL of DMSO was stirred at 100° C. overnight. After cooling, to the reaction mixture was added water, followed by extraction with ethyl acetate, and then drying over anhydrous sodium sulfate. After filtration, the filtrate was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (hexane-ethyl acetate) to obtain 147 mg of methyl 4-[(3R,4S)-3-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-4-(2-fluorophenyl)piperidin-1-yl]-3,5-difluorobenzoate as a colorless amorphous substance.
