Reaction Steps

1-(2-Hydroxyethyl)-5-chloropyrimid-2-one (0.001 mol) and phosphorus oxychloride (5 ml) were heated together at 80° C. for 60 min. before the solution was evaporated at reduced pressure. The residue was triturated with chloroform before dissolution in water (4 ml) and neutralisation with sodium bicarbonate. Chloroform extraction and evaporation left a solid which was recrystallised from ethyl acetate, yield 52%, m.p. 167°-168° C. (Found: C, 37.20; H, 3.20; Calc for C6H6Cl2N2O: C, 37.34; H 3.13).
