Procedure

1.0 g of water-moist Raney nickel is added to a solution of 2.60 g (10.7 mmol) of 2-(4-nitrophenyl)isothiazolidine 1,1-dioxide in 50 ml of tetrahydrofuran, and the mixture is hydrogenated at room temperature. The catalyst is filtered off, and the filtrate is evaporated, giving 2-(4-aminophenyl)isothiazolidine 1,1-dioxide as a brownish solid; ESI 213.
