Reaction Steps
A solution of 4.17 g of 5-fluoro-2-(3-methoxyphenoxy)-4-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]nitrobenzene in 10 ml of acetic acid was added dropwise over 20 minutes to a mixture of 4.5 g of iron powder, 10 ml of acetic acid and 1 ml of water. After the addition, the mixture was stirred for 2 hours, filtered through celite and diluted with ethyl acetate. The resultant was washed with water 2 times, the organic layer was washed with 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 3.67 g of 5-fluoro-2-(3-methoxyphenoxy)-4-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]aniline.
