Reaction Steps

A suspension of 3-(2′,4′-dichlorobiphenyl-4-ylsulfonamido)benzoic acid (1.50 g, 3.56 mmol) in DCM (35 mL) was stirred at 0° C. and oxalyl chloride (340 μL, 3.9 mmol) was added, followed by a catalytic amount of DMF (<50 μL). The mixture was allowed to warm to room temperature and stirred for two days, during which time the solid dissolved to form a light yellow clear solution. The mixture was evaporated under reduced pressure and the residue was azeotroped with toluene (3 mL), then hexane (10 mL) and the title compound obtained as a light brown, slightly gummy, solid (1.5 g) which was used without further purification.
