Procedure
5-methoxy-1-benzenesulfonyl-2-sulfamoylindole (22.0 gm, 0.97 mmol) was dissolved in 10% sodium hydroxide (250 ml) and warmed to 90° C. for 1 hour. The cooled reaction mixture was extracted with ethyl acetate (2×150 ml) and neutralized with concentrated hydrochloric acid. The precipitate was collected via filtration and the filtrate was extracted with ethyl acetate (4×200 ml). The precipitate collected earlier was combined with the extracts and the extracts were washed with water (2×100 ml), brine (2×100 ml) and dried (MgSO4). The organic solvent was removed under vacuum to yield a brown solid 10.2 gm. The solid was recrystallized from water using decolorizing carbon to yield white crystals; 4.5 gm., m.p. 208°-209° C.
