Reaction Steps

To 2-hydroxyethylamine (2.6 g, 42.7 mmol) were added 2-amino-4,6-dichloropyrimidine (7.0 g, 42.7 mmol), ethanol (150 ml) and triethylamine (6.6 ml), and the mixture was refluxed for one day. The solvent was distilled away under reduced pressure and the residue was washed with water, which was followed by recrystallization from chloroform to give yellow prism crystals (4.8 g, 59.6%), m.p. 143-146° C. (chloroform).
