Procedure
To a slurry of 1.8 g (0.028 mole) of potassium cyanide in 80 ml of dimethylsulfoxide at 60° C. was added 9.7 g (0.027 mole) of 7-(bromomethyl)-3-(2,4-dichlorophenyl)-2,1-benzisoxazole. The mixture was heated at 50°-60° C. for 3 hr, poured into 1 liter of water and let stand overnight. The resulting solid was collected by filtration, washed with water and dried to give 7.6 g of crude tan solid. The solid was chromatographed on 160 g of silica gel to give 2.7 g of solid. The solid was recrystallized from carbon tetrachloride (charcoal) and then from acetonitrile to yield 0.7 g (8%) of crystals, m.p. 147°-148° C.
