Procedure

To a mixture of 0.4 g of an iron powder, 2 ml of acetic acid and 0.2 ml of water was added a solution of 0.393 g of 5-{4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]-2-nitrophenoxy}-4-(methoxycarbonyl)methoxypyrimidine in 1 ml of acetic acid and 2 ml of ethyl acetate dropwise. After completion of the addition, the mixture was stirred for 1 hour at room temperature, for 2 hours at 30-40° C. Water was added to the mixture, then, the mixture was filtrated through Celite, and extracted with ethyl acetate. The organic layer was washed with saturated aqueous sodium bicarbonate solution, and saturated saline, dried over anhydrous magnesium sulfate, and concentrated. Then, the resulted residue was subjected to silica gel chromatography to obtain 0.315 g of 5-{2-amino-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-4-(methoxycarbonyl)methoxypyrimidine.
