Reaction Steps

0.14 g of 1-Isopropyl-4-(1-(4-fluorophenyl)-2-{4-[4-(2-methoxynaphthalen-1-yl)butyl]piperazin-1-yl}-2-oxoethyl)piperidine was dissolved in 5 ml of tetrahydrofuran, and 10 ml of lithium aluminum hydride was added, followed 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 0.13 g of 1-[2-(4-fluorophenyl)-2-(1-isopropylpiperidin-4-yl)ethyl]-4-[4-(2-methoxynaphthalen-1-yl)butyl]piperazine as an oil.
