Procedure
The title compound was synthesized as described for Example 178 in 48% yield, starting from 2-aminobenzenesulfonamide and 3-bromobenzenesulfonyl chloride. The product solidified after the extractive work up. Diethyl ether (25 mL) was added and the crystals were crushed with a glass stick. The mixture was filtered and the solid was rinsed with diethyl ether and dried in vacuo at ambient temperature.
