Versuchsvorschrift
6-Bromo-4-chloropyrido[2,3-d]pyrimidine (1.0 g) and 4% NH3 in i-PrOH (25 mL) were stirred in a sealed tube at room temperature overnight. The pale brown heterogeneous slurry was concentrated, diluted with water and filtered. The brown solid thus collected was suction dried to obtain 6-bromopyrido[2,3-d]pyrimidin-4-amine (1.3 g, purity: 97%). 1H NMR (300 MHz, DMSO-d6) δ 9.09 (d, J=2.5 Hz, 1H), 9.01 (d, J=2.5 Hz, 1H), 8.52 (s, 1H), 8.31 (br s, 2H).
