26.9 g of 3-nitro-4-(phenylthio)-benzotrifluoride in 250 ml of ethanol are hydrogenated in the presence of 10 g of Raney-nickel at room temperature and atmospheric pressure for 17 hours. The mixture is filtered and evaporated under reduced pressure. There is obtained 3-amino-4-(phenylthio)-benzotrifluoride as a red-brown oil. The compound is distilled under greatly reduced pressure and boils at 110°-135° C/0.1 mm; orange-coloured oil.
