Procedure

0.20 g of 4-(1-(4-Fluorophenyl)-2-{4-[4-(2-methoxynaphthalen-1-yl)butyl]piperazin-1-yl}-2-oxoethyl)piperidine hydrochloride obtained in Example 11(5) was dissolved in 2 ml of dimethylformamide, and 93 mg of potassium carbonate and 41 μl of 2-iodopropane were added, followed by stirring at room temperature overnight. The reaction solution was diluted with ethyl acetate and washed with a saturated aqueous sodium bicarbonate solution and a saturated aqueous sodium chloride solution. The organic layer was dried over anhydrous sodium sulfate. After removal of the drying agent by filtration, the filtrate was concentrated under reduced pressure. The residue was purified by a silica gel column chromatography (Chromatorex NH, hexane:ethyl acetate=4:1) to give 0.15 g of 1-isopropyl-4-(1-(4-fluorophenyl)-2-{4-[4-(2-methoxynaphthalen-1-yl)butyl]piperazin-1-yl}-2-oxoethyl)piperidine as an oil.
