Procedure

To a mixture of 400 mg of 2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenol, 377 mg of 6-methoxy-4-{1-(methoxycarbonyl)ethoxy}-2-methylsulfonylpyrimidine and 3 ml of N,N-dimethylformamide, 196 mg of potassium carbonate was added, and the mixture was stirred for 1 hour at 80° C. The reaction solution was cooled to room temperature, then, this reaction solution was poured into water, and extracted with ethyl acetate. The organic layer was washed with saturated saline, dried over anhydrous magnesium sulfate, and concentrated. The residue was subjected to silica gel column chromatography to obtain 630 mg of 2-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-6-methoxy-4-{1-(methoxycarbonyl)ethoxy}pyrimidine [present compound 1-42].
