Versuchsvorschrift

A stirred mixture of 6-fluoro-3-(4-piperidinyl)-1,2-benzisoxazole (9.25 g, 42 mmol), K2CO3 (8 g, 58 mmol) and 3-(3-acetamidophenoxy)propyl bromide (11.4 g, 42 mmol) in acetonitrile (350 ml) was heated at reflux for 3 hours. At the end of the reaction, the reaction was cooled, filtered and the solids washed with dichloromethane (100 ml). The organic solvent was removed on a rotary evaporator to leave a crude oil (18 g). Purification was by flash chromatography on a silica gel column. The product thus purified was an oil, 12.2 g, 70%. Analytically pure sample was prepared by dissolving 3 g of free base in ethanol and treating with fumaric acid solution in ethanol (850 mg:5ml). The N-[3-[3-[4-(6-fluoro-1,2-benzisoxazol-3-yl)-1-piperidinyl]propoxy]phenyl]acetamide hemifumarate crystals obtained weighed 2.73 g, m.p.=184°-186° C.
