Conditions

Temperature: 0 °C

Procedure

At 0° C., 1.5 g (4.3 mmol) of N-{5-[4-(trifluoromethyl)phenyl]piperidin-3-yl}benzamide and 1.2 ml (1.1 mmol) of triethylamine were initially charged in 131 ml of dichloromethane, and 868 mg (4.3 mmol) of 4-nitrophenyl chlorocarbonate were added slowly. The mixture was stirred at 0° C. for 2 h and then warmed to RT. Water and saturated aqueous sodium bicarbonate solution were added, and the reaction mixture was extracted. The organic phase was concentrated under reduced pressure and purified by column chromatography (cyclohexane/ethyl acetate 1:2). Yield: 1.95 g (88% of theory)
