Procedure
3-chlorosulfonyl-2-[trans-3,4-(methylenedioxy)cinnamyl]thiophene was prepared in the same manner as described in Example 1 5E from N-{2-[trans-3,4-(methylenedioxy)cinnamyl]thiophene-3-sulfonyl}pyrrole by basic hydrolysis (using isopropanol and potassium hydroxide) to the corresponding potassium sulfonate (100%) followed by conversion of the salt to the corresponding sulfonyl chloride in a 31% overall yield.
