Procedure
2-Fluoro-N-(4-bromo-3-methyl-5-isoxazolyl)benzenesulfonamide was prepared from 5-amino-4-bromo-3-methylisoxazole and 2-fluorobenzenesulfonyl chloride according to the procedures described in Example 25b. The crude product was purified by recrystallization from ethyl acetate/hexanes to give a white solid, m.p. 87-89° C., yield 44%.
