0.25 g of 4-{1-(4-Fluorophenyl)-2-[4-(naphthalen-1-yl-butyl)piperazin-1-yl]-2-oxoethyl}-1-methylpiperidin-4-ol was dissolved in 3 ml of tetrahydrofuran, and 18 mg of lithium aluminum hydride was added, followed by stirring at 50° C. for 15 minutes. The reaction solution was cooled to room temperature and diluted with ether, and 25% aqueous ammonia solution was added dropwise. The precipitate was removed by Celite filtration, the filtrate was concentrated under reduced pressure, and the residue was purified by a silica gel column chromatography (Chromatorex NH, hexane:ethyl acetate=4:1) to give 33 mg of 4-{1-(4-fluorophenyl)-2-[4-(naphthalen-1-yl-butyl)piperazin-1-yl]ethyl}-1-methylpiperidin-4-ol as an oil.
