Reaction Steps

N-(4-Bromo-3-methyl-5-isoxazolyl)-4,5-dibromo thiophene-2-sulfonamide was prepared in the same manner as described in Example 2 from 5-amino-4-bromo-3-methylisoxazole and 4,5-dibromothiophene-2-sulphonyl chloride in 45% yield. Purification was achieved by recrystallization from ethyl acetate/hexanes to give a crystalline solid, m.p. 153°-155° C.
