Procedure

2-[(4-methyl)phenethyl]thiophene-3-sulfonylchloride was prepared, as described in Example 15E, using N-{2-[(4-methyl)phenethyl]thiophene-3-sulfonyl}pyrrole by basic hydrolysis (KOH/ethanol) of the sulfonamide to this potassium salt followed by conversion of salt to the corresponding sulfonyl chloride in 51% yield.
