A solution of 2-[3-(3-acetamidophenyl)phenylamino]-3-nitropyridine (10 g) in 3N hydrochloric acid (100 ml) was refluxed for 2 hours. The cold reaction was adjusted to pH 8 with saturated sodium bicarbonate solution and precipitated reddish crystals were collected, washed with water and dried to give 2-[3-(3-aminophenyl)phenylamino]-3-nitropyridine (9.53 g).
