Procedure
N-(4-bromo-3-methyl-5-isoxazolyl)-2-[trans-3,4-(methylenedioxy)-cinnamyl]thiophene-3-sulfonamide was prepared in the same manner as described in Example 1 by reaction of 3-chlorosulfonyl-2-[trans-3,4-(methylenedioxy)cinnamyl]thiophene with 5-amino-4-bromo-3-methylisoxazole. The crude product was purified by HPLC resulting in a 33% yield, m.p. 147-149° C.
