Versuchsvorschrift

A solution of methyl amine-ethanol (7.6 ml) and N,N-diisopropylethylamine (13.2 ml) were dissolved into 150 ml dichloromethane. The mixture was added dropwise to a solution of 2,4-dichloro-5-nitropyrimidine (10.0 g) in dichloromethane (30 ml) at 0° C. After the completion of the dropwise addition, the mixture was kept at the same temperature to react for half an hour. Purification was conducted by a column chromatography to obtain a yellow solid (8.3 g) in a yield of 85.4%. 1H NMR (400 MHz, CDCl3): δ 9.05 (s, 1H), 8.41 (s, 1H), 3.22 (s, 3H) ppm.
