Procedure

The compound 4-methyl-3-nitro-benzene-N,N-dimethylsulfonamide is dissolved in ethanol. A catalyst like Raney nickel is added and the mixture hydrogenated in a shaker. The catalyst is removed by filtration. The solvent is removed in vacuo to give a product which may be purified if necessary by chromatography or crystallization from an appropriate solvent like chloroform or heptane-ethyl acetate.
