To a mixture of 1-[(pyridin-3-yloxy)carbonyl]piperidine-4-carboxylic acid (500 mg) and DCM (10 mL) were added HOBt (297 mg) and WSC hydrochloride (498 mg), followed by stirring at room temperature for 30 minutes. Then, 2-amino-1-(2-fluorophenyl)ethanone hydrochloride (417 mg) and triethylamine (0.31 mL) were added thereto, followed by stirring at room temperature overnight. The reaction liquid was purified directly by silica gel column chromatography (chloroform/methanol=99/1 to 95/5) to obtain pyridin-3-yl 4-{[2-(2-fluorophenyl)-2-oxoethyl]carbamoyl}piperidine-1-carboxylate (423 mg) as a colorless solid.
