2.6 g of 2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenol and 1.7 g of 4-benzyloxy-2-chloropyrimidine were dissolved in 20 ml of N,N-dimethylformamide, to this solution was added 1.07 g of potassium carbonate, and the mixture was stirred for 2 hours at 80° C. The reaction solution was cooled to room temperature, then, this reaction solution was poured into ice water, and extracted with ethyl acetate. The organic layer was washed with 10% aqueous sodium hydroxide solution, dried over anhydrous magnesium sulfate, and concentrated to obtain 1.6 g of 4-benzyloxy-2-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}pyrimidine.
