Reaction Steps
A solution of 2,5-diamino-4,6-dichloro-pyrimidine (0.001 mol; 2.0 g) and 98% strength formic acid (0.5 mol, 22.96 g, 18.8 ml) was stirred overnight at room temperature. Toluene (0.94 mol, 86.76 g, 18.82 ml) was then added and the reaction was cooled to 0-5° C. The product was filtered off and washed with water (1.11 mol, 20.0 g, 20.0 ml). The product was subsequently dried at 50° C. in vacuo. N-(5-Amino-4,6-dichloropyrimidin-2-yl)formamide was detected in the 1H NMR as a single product. 0.01 mol (1.62 g) of the abovementioned product was obtained, corresponding to a yield of about 70%.
