실험 절차

To 40 ml of dimethylformamide was added 5.3 g of 4-(3-methoxyphenyl)piperazine dihydrochloride, 6.4 g of 3-(3-chloropropyl)-6-fluoro-1,2-benzisoxazole, 10.0 g of milled potassium carbonate, and 0.01 g of potassium iodide. The mixture was stirred at 90° C. for two hrs, cooled, filtered, and evaporated to an oil. The oil was stirred with 100 ml water for ten mins, and extracted with ether. The ether extract was washed with water (2×), saturated sodium chloride solution and dried over anhydrous magnesium sulfate. After filtering, ethereal oxalic acid was added and the resulting precipitate was collected and dried to give 3.8 g (41%) of product. Two recrystallizations from ethyl acetate/methanol/ether (10:1:5), gave the analytical sample, mp 168° C. (dec).
