Procedure

14 mg (41.3 mmol) of 5-(4-acetoxymethylbenzoyl)-3-thiophene sulfonamide and 9 mg (61.8 mmol) of K2CO3 were added to 3 mL of methanol. After stirring at rt for 11 h the solution was diluted with ethyl acetate and washed with 1N HCl followed with water (2×) and brine. The solvent was removed under vacuum to afford 12.5 mg of 5-(4-hydroxymethylbenzoyl)-3-thiophene sulfonamide as a white solid.
