Reaction Steps

Isoamyl nitrite is added to a mixture of 5-{2-amino-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-4-{1-(methoxycarbonyl)ethoxy}-2-methylpyrimidine, copper(I) chloride, copper(II) chloride and acetonitrile dropwise at room temperature, and the mixture is stirred for 1 hour. This reaction solution is poured into 2% hydrochloric acid, and extracted with ethylacetate. The organic layer is washed with saturated saline, dried over anhydrous magnesium sulfate, and concentrated. The residue is subjected to silica gel column chromatography to obtain 5-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-4-{1-(methoxycarbonyl)ethoxy}-2-methylpyrimidine [present compound4-76].
