Procedure

To the solution of 4,6-dichloro-2-methylsulfanyl-pyrimidine-5-carbaldehyde (2 g, 7.36 mmol) in benzene (20 mL) was introduced NH3 gas for 30 minutes (hereinafter “min”). The formed solid was then filtered and recrystalized from EtOAc (15 mL) to give 1.18 g (80%) of pure 4-amino-6-chloro-2-methylsulfanyl-pyrimidine-5-carbaldehyde. 1H-NMR: δ 2.50 (s, 3H), 7.28 (t, 3H, J=45 Hz, D2O exchangeable), 8.65 (d, 3H, J=41 Hz, D2O exchangeable), 10.11 (s, 1H).
