2-Amino-6-chloro-4-hydroxyquinoline (CAS 64319-84-2, 6.0 g, 31 mmol) were added portionswise to phosphorus tribromide (25 g, 92 mmol). Phosphorus oxybromide (10 g, 37 mmol) were added and the mixture was stirred at 150° C. for 16 h. The mixture was poured into 300 mL ice water and the pH was adjusted to 11 by addition of 32% sodium hydroxide solution. The solid was filtered off and washed with water and cyclohexane. 4-Bromo-6-chloro-quinolin-2-ylamine was obtained as a yellow solid (7.8 g, 98%), MS: m/e=258.9 (M+H+).
