Procedure

To a mixture of 0.93 g of methyl [2 -{2-chloro-4-fluoro-5-[2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}phenoxy]acetate, 0.31 g of potassium carbonate, and 10 ml of N,N-dimethylformamide was added 0.58 g of methyl iodide, and the mixture was stirred at room temperature for 2 hours. Then 50 ml of diluted hydrochloric acid was added, and the mixture was extracted with ethyl acetate. The organic layer was washed with water, saturated aqueous sodium chloride solution, dried over anhydrous sodium sulfate, and then concentrated under reduced pressure. The residue was subjected to silica gel column chromatography to give 0.82 g of methyl [2-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}phenoxy]acetate (compound a-5).
