Reaction Steps

0.3 g of isoamyl nitrite was added to a mixture of 0.83 g of 5-{2-amino-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-2-(methoxycarbonyl)methoxypyridine, 0.34 g of copper(I) chloride, 0.69 g of copper(II) chloride and 3 ml of acetonitrile dropwise at room temperature, and the mixture was stirred for 1 hour. 0.3 g of isoamyl nitrite was added to the mixture, and stirred for 20 minutes. This reaction solution was poured into 2% hydrochloric acid, 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 0.52 g of 5-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-2-(methoxycarbonyl)methoxypyridine [present compound 7-17].
