Procedure

A suspension of 3-(4-bromophenylsulfonamido)benzoic acid (2.30 g, 6.46 mmol) in DCM (50 mL) was stirred and cooled under argon to 0° C. Oxalyl chloride (676 μL, 7.11 mmol) was then added dropwise via a syringe, followed by DMF (50 μL). The resulting solution was then stirred overnight, allowing the reaction mixture to warm room temperature. The solution was used without further purification.
