実験手順

A solution of 200 mg of tert-butyl[(1R)-1-(1-naphthyl)ethyl][(4-phenylpiperidin-3-yl)methyl]carbamate, 212 mg of 3,4,5-trifluorobenzonitrile, and 187 mg of potassium carbonate in 4.0 mL of DMSO was heated at 110° C. for 2 hours. The reaction mixture was cooled to room temperature, and water was added thereto, followed by extraction with ethyl acetate. The organic layer was washed with water and saturated brine in this order, and dried 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 191 mg of tert-butyl {[1-(4-cyano-2,6-difluorophenyl)-4-phenylpiperidin-3-yl]methyl}[(1R)-1-(1-naphthyl)ethyl]carbamate as a colorless foamy substance. ESI+: 582
