Reaction Steps

0.27 g (0.0009 mol) of 1,3-dimethyl-5-(4-nitrobenzenesulphonyl)-benzene was suspended in 40 ml of ethanol, treated with 0.03 g of Pd/C (10%) and stirred in a H2 atmosphere at room temperature under normal pressure for 2 hrs. Then, the catalyst was filtered off, the filtrate was freed from solvent and the residue was chromatographed on silica gel with ethyl acetate/hexane 2:1. There was obtained 0.157 g (73%) of 4-(3,5-dimethylbenzenesulphonyl)-phenylamine as white crystals; m.p.: 178-179° C.
