Procedure

3-Nitro-N-(4-bromo-3-methyl-5-isoxazolyl)benzenesulfonamide was prepared in the same manner as described in Example 30 from 5-amino-4-bromo-3-methylisoxazole and 3-nitrobenzenesulfonyl chloride in 55% yield. Purification was achieved by recrystallization from ethyl acetate/hexanes to give a crystalline solid, m.p. 151-153° C.
