To a suspension of N-(piperidin-4-yl)-4-fluorobenzamide (556 mg) in dichloromethane (5 ml) were added pivaloyl chloride (0.37 ml), pyridine (0.24 ml) and N,N-dimethylaminopyridine (25 mg) at ambient temperature. After stirring for 1 day, the mixture was diluted with dichloromethane, and washed with water and brine. After drying with magnesium sulfate, the solvents were removed under reduced pressure. After trituration with diisopropyl ether, N-(1-pivaloylpiperidin-4-yl)-4-fluorobenzamide (305 mg) was obtained.
