Procedure

To ethyl [2-{2-chloro-4-fluoro-5-[2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}phenoxy]acetate, are added N,N-dimethylformamide and potassium carbonate, then, methyl iodide is added to the reaction solution, and the mixture is stirred at room temperature. Diluted hydrochloric acid is added to the reaction solution and extracted with ethyl acetate. The organic layer is washed with water and then saturated saline, and dried over anhydrous magnesium sulfate, and concentrated. The residue is subjected to silica gel column chromatography to obtain ethyl [2-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}phenoxy]acetate [compound 3-12 of the present invention].
