Procedure

30 mg of sodium hydride was added to a mixture of 0.3 g of 2-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-4-hydroxy-pyrimidine, 127 mg of methyl bromoacetate and N,N-dimethylformamide at 0° C., then, the mixture was stirred at room temperature. The solution was poured into a mixture of ice water, and extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate, and concentrated. The residue was subjected to silica gel column chromatography to obtain 0.2 g of 2-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-4-(methoxycarbonyl)methoxypyrimidine [present compound 1-7].
