Procedure

A mixture of 11.02 g of isoamyl nitrite and 45 ml of acetonitrile was added dropwise to a mixture of 15.16 g of methyl [2-{2-amino-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}phenoxy]acetate, 6.21 g of copper (I) chloride, 12.65 g of copper (II) chloride, and 250 ml of acetonitrile at room temperature, and the mixture was stirred for 2 hours. The reaction mixture was poured into 2% hydrochloric acid, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated aqueous sodium chloride solution, dried over anhydrous magnesium sulfate, and then concentrated. The residue was subjected to silica gel column chromatography to give 13 g of methyl [2-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}phenoxy]acetate (compound a-5).
