Reaction Steps

In 5 ml of dichloromethane, 0.50 g (1.5 mmol) of 1-(α-cyclopropylcarbonyl-2-fluorobenzyl)-4-mercaptopiperidine hydrochloride were dissolved, followed by the addition of 0.3 g (3 mmol) of triethylamine. To the resulting mixture, a solution of 0.16 g (1.5 mmol) of butyryl chloride in 1 ml of dichloromethane was added dropwise under ice cooling and the resulting mixture was stirred at room temperature for 1 hour. Water was added to the reaction mixture, followed by extraction with dichloromethane. The extract was dried over anhydrous sodium sulfate. The solvent was concentrated by evaporation under reduced pressure and the residue was subjected to chromatography on a silica gel column (eluting solvent: toluene/ethyl acetate=30/1), whereby 0.32 g (yield: 58%) of the title compound was obtained as white crystals.
