実験手順

To a solution of 19 g of iron powder, 60 ml of acetic acid and 6 ml of water, a solution of 19.12 g of 5-fluoro-2-{2-(methoxycarbonyl)methoxyphenoxy}-4-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]nitrobenzene [Compound 4-19 of the present invention] in 60 ml of acetic acid was added dropwise under ice cooling. After the addition, the temperature of the reaction mixture was raised to room temperature and the mixture was stirred for 4 hours. The reaction mixture was filtered with sellaite and diluted with ethyl acetate. The dilution was washed with water, saturated aqueous sodium bicarbonate solution and saturated saline, dried over anhydrous magnesium sulfate, and concentrated. The residue was subjected to silica gel column chromatography to obtain 15.16 g of 5-fluoro-2-{2-(methoxycarbonyl)methoxyphenoxy}-4-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]aniline.
