Reaction Steps
3.0 gm (13 mmols) of 4-nitro-1,2-benzoisothiazol-3(2H)-one-1,1-dioxide were dissolved in 100 ml of ethanol. The solution was hydrogenated with hydrogen, using a palladium/animal charcoal catalyst. After filtration, evaporation and recrystallization from ethanol 2.3 gm (89.5% of theory) of the amino compound were obtained.
