Reaction Steps

A mixture of 1.6 g of 7-acetyl-2-chloroethyl-5,6,7,8-tetrahydro-4H-thieno[2,3-c]azepine, 1.8 g of 4-(6-fluoro-1,2-benzisoxazol-3-yl)-piperidine hydrochloride, 2.6 g of potassium carbonate and 1 g of potassium iodide in 15 ml of dimethylformamide and 15 ml of toluene was stirred at 90° C. for 5 hours and concentrated in vacuo. To the residue were added ethyl acetate and water, and separated. The ethyl acetate layer was washed with water, dried over magnesium sulfate and concentrated in vacuo. The residue was purified by column chromatograhy on a silica gel to give 1.5 g of 7-acetyl-2-(2-(4-(6-fluoro-1,2-benzisoxazol-3-yl)piperidin-1-yl)ethyl)-5,6,7,8-tetrahydro-4H-thieno[2,3-c]azepine as an oil. The oil was treated with hydrochloric acid in isopropyl alcohol and recrystallized from ethanol-isopropyl ether to give 7-acetyl-2-(2-(4-(6-fluoro-1,2-benzisoxazol-3-yl)piperidin-1-yl)ethyl)-5,6,7,8-tetrahydro-4H-thieno[2,3-c]azepine hydrochloride 3/2hydrate, m.p. 210° C. (decomposition).
