Procedure

N-(4-bromo-3-methyl-5-isoxazolyl)-5-(3-tolyl) thiophene-2-sulfonamide was prepared in the same manner as described in the Example 117C using 2-chlorosulfonyl-5-(3-tolyl)thiophene and 5-amino-4-bromo-3-methylisoxazole. To obtain the ammonium salt of the final product, aqueous NH4OH was used (31% yield; hygroscopic).
