Reaction Steps

To a mixture of 0.15 g of 5-hydroxy-4-(methoxycarbonyl)methoxy-2-methylpyrimidine, 0.16 g of 2,5-difluoro-4-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]nitrobenzene and 2 ml of N,N-dimethylformamide was added 74 mg of potassium carbonate, and the mixture was stirred for 1 hour at 70° C. The reaction solution was cooled to room temperature, then, poured into ice 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 0.20 g of 5-{4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]-2-nitrophenoxy}-4-(methoxycarbonyl)methoxy-2-methylpyrimidine.
