Reaction Steps

A solution of 4-bromobenzenesulfonyl chloride (1.34 g, 5.25 mmol), 3-aminobenzenesulfonamide (860 mg, 5.0 mmol) and DIPEA (1.29 g, 10 mmol) in THF (10 mL) was stirred overnight at room temperature. The solvent was then evaporated and the residue purified by chromatography on the SP4 (70 g Silica Isolute II, 0-100% EtOAc/hexane) to and the title compound obtained as a white solid (395 mg).
