Reaction Steps

A mixture of 0.9 g of 6-acetyl-2-(2-chloroethyl)-3-ethyl-4,5,6,7-tetrahydrothieno[2,3-c]pyridine, 1.0 g of 4-(4,6-dichlorobenzo(b)furan-3-yl)piperidine hydrochloride, 0.5 g of potassium carbonate, 0.5 g of potassium iodide, 25 ml of dimethylformamide and 25 ml of toluene was stirred at 80° C. for 6 hours and then poured into water. The toluene layer was washed with water, dried over anhydrous magnesium sulfate and concentrated. The residue was purified by column chromatography on a silica gel and then dissolved into ethanol to make a hydrochloride. The resulting crystals were recrystallized from isopropyl alcohol to give 6-acetyl-2-(2-(4-(4,6-dichlorobenzo(b)furan-3-yl)piperidin-1-yl)ethyl)-3-ethyl-4,5,6,7-tetrahydrothieno[2,3-c]pyridine hydrochloride, m.p. 260° C. (decomposition).
