실험 절차

A mixture of 1.5 g of 2-(4-fluorophenyl)-2-(3-chloropropyl)-1,3-dioxolane, 1.5 g of 4-(6-fluorobenzo[b]thiophen-3-yl)piperidine hydrochloride, 3.3 ml of diisopropylethylamine and 2.5 ml of methanol was stirred with heating under reflux for 25 hours. The reaction mixture was separated with chloroform and a saturated aqueous sodium hydrogencarbonate solution, and the aqueous layer was extracted with chloroform. The combined organic layer was washed with water and a saturated aqueous sodium chloride solution and then dried over magnesium sulfate. The solvent was distilled off under reduced pressure, and the residue was purified by a flush chromatography (silica gel: Merckkieselgel 60 230- to 400-mesh, eluent: hexane-ethyl acetate=1:2) to obtain 0.71 g of 2-(4-fluorophenyl)-2-[3-[4-(6-fluorobenzo[b]thiophen-3-yl)piperidin-1-yl]propyl]-1,3-dioxolane.
