Procedure
4-Fluoro-N-(4-bromo-3-methyl-5-isoxazolyl)benzenesulfonamide was prepared in the same manner as described in Example 5 from 5-amino-4-bromo-3-methylisoxazole and 4-fluorobenzenesulfonyl chloride in 71% yield. Purification was achieved by recrystallization from ethyl acetate/hexanes to give a crystalline solid, m.p. 142°-144° C.
