Reaction Steps

A solution of 2-amino-5-chlorobenzenesulfonamide (0.041 g, 0.20 mmol) and (E)-2-(4-chloro-2-methoxyphenyl)ethenesulfonyl chloride (0.053 g, 0.20 mmol) in pyridine (2 mL) was stirred at room temperature over night. The reaction mixture was concentrated, 1 M hydrochloric acid was added and the mixture was extracted with dichloromethane. The organic phase was dried over magnesium sulfate and the solvent was evaporated to give 0.087 g (99% yield) of the title compound.
