4-Benzenesulfinyl-benzoic acid (0.14 g, 0.5 mmol) was suspended in sodium hypochlorite solution (10 mL) and the reaction mixture stirred for 24 h at room temperature. The progress of the reaction was monitored by TLC. The reaction mixture was acidified with an aq. solution of 10% HCl solution. The resulting precipitate was filtered and washed with water. The residue was then redissolved in methanol and concentrated to get the title compound (0.105 g, 70%).
