To a suspension of 2-methoxy-5-phenoxysulfonylbenzoic acid (4.0 g, 13 mmol) in dry toluene (100 mL) was added oxalyl chloride (2.3 mL, 26 mmol) at room temperature. A drop of DMF was added and the mixture stirred at room temperature for 2 h. The mixture was evaporated in vacuo and the residue triturated with 1:1 toluene/hexane to give the title compound as a solid (4.04 g).
