실험 절차

A mixture of 0.7 g of 6-acetyl-2-(2-chloroethyl)-3-ethyl-4,5,6,7-tetrahydrothieno[2,3-c]pyridine, 0.7 g of 4-(6-fluorobenzo(b)thiophen-3-yl)piperidine hydrochloride, 1.8 g of potassium carbonate and 0.6 g of potassium iodide in 25 ml of dimethylformamide and 25 ml of toluene was stirred at 70° C. for 7 hours and poured into water. The toluene layer was washed with water, dried over magnesium and concentrated. The residue was purified by column chromatography on a silica gel and dissolved in ethanol to convert hydrochloride thereof, and then recrystallized from methanol to give 0.45 g of 6-acetyl-3-ethyl-2-(2-(4-(6-fluorobenzo-(b)thiophen-3-yl)piperidin-1-yl)ethyl)-4,5,6,7-tetrahydrothieno[2,3-c]pyridine hydrochloride, m.p. 240° C. (decomposition).
