Reaction Steps

0.25 g of 4-{1-(4-Fluorophenyl)-2-[4-(4-naphthalen-1-yl-butyl)piperazin-1-yl]-2-oxoethyl}-1-methyl-3,6-dihydro-2H-pyridine 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 0.10 g of 1-[2-(4-fluorophenyl)-2-(1-methyl-1,2,3,6-tetrahydropyridin-4-yl)ethyl]-4-(4-naphthalen-1-yl-butyl)piperazine as an oil.
