3.7 g (12.7 mmol) of 4-(4-methoxy-2-trifluoromethyl-phenylamino)-benzonitrile were hydrogenated in a 7N solution of ammonia in methanol (100 mL) with the addition of Raney nickel at ambient temperature. After the catalyst had been filtered off and the solvent distilled off, the crude product thus obtained was reacted further without purification.
