反応条件

温度160 °C

反応手順

50 mg (0.230 mmol) I) of 2-amino-5-bromonicotinic acid and 27.6 mg (0.253 mmol) of pyridine-2,3-diamine are added to 451.5 mg (5 mmol) of polyphosphoric acid, and the mixture is stirred at 160° C. for 4 days. The reaction mixture is cooled to room temperature, water is added, and the mixture is adjusted to pH 12 by means of 1N NaOH. The precipitate formed is filtered off with suction and dried, giving 5-bromo-3-(1H-imidazo[4,5-b]pyridin-2-yl)pyridin-2-ylamine.
