Reaction Conditions

Reaction Steps

A mixture of 2-amino-3-(4-chloro-3-ethoxycarbonylphenyl)-3,4-dihydro-6-trifluoromethylpyrimidin-4-one (0.5 g), bromoacetone dimethyl acetal (0.6 g) and DMF (10 ml) was heated for 5 hours at 130° C. with stirring. The solvent was distilled off under reduced pressure. The residue was added with water and extracted with ethyl acetate. The extract layer was washed with water and dried on anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure and the residue was purified by a preparative thin-layer plate of alumina (developing solvent: ethyl acetate/hexane=3/7) to give the compound of interest (0.11 g).
