Reaction Steps

A stirred suspension of 5-chloropyrimidin-2-one (2.610 g), potassium carbonate (55 mg) and 1-bromo-2,3-epoxypropane (3.42 ml) in dry N,N-dimethylformamide (40 ml) was heated at 80° C. After 23/4 h the reaction mixture was evaporated and the residue was subjected to column chromatography on silica developing and eluting with chloroform-ethanol, 19:1. This gave an off white solid which was triturated with ethyl acetate to give white crystals of the title pyrimidinone (1.483 g), m.p. 166°-170° C., λmax (EtOH) 227 nm (ε 9,740).
