실험 절차

To 40 ml of dimethylformamide was added, 5.0 g of 1-(2-chlorophenyl)piperazine hydrochloride hydrate, 6.4 g of 3-(3-chloropropyl)-6-fluoro-1,2-benzisoxazole, 10 g of milled potassium carbonate, and 0.01 g of potassium iodide, and the mixture was stirred at 90° C. for 2 hrs. The mixture was cooled, filtered and the filtrate evaporated to an oil. The oil was stirred with 100 ml water for five mins and then extracted with ether. The ether extract was washed with water (2×), saturated sodium chloride solution, and dried over anhydrous magnesium sulfate. After filtering, the solution was acidified to pH 1 with ethereal hydrogen chloride, and the precipitate was collected and dried to give 5.7 g (70%) of product, mp 195° C. (dec). Two recrystallizations from ethyl acetate/methanol (5:1) gave the analytical sample, mp 228° C. (dec).
