Reaction Steps

N-(4-Bromo-3-methyl-5-isoxazolyl)-5-(benzenesulfonyl)thiophene-2-sulfonamide was prepared in the same manner as described in Example 2 from 5-amino-4-bromo-3-methylisoxazole and 5-benzenesulfonylthiophene-2-sulfonyl chloride in 59% yield. Purification was achieved by recrystallization from ethyl acetate/hexanes to give a crystalline solid, m.p. 139°-142° C.
