Procedure

A solution of 10.99 g of isoamyl nitrite in 10 ml of acetonitrile was added to a mixture of 15.46 g of ethyl 2-[3-{2-amino-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-2-pyridyloxy]propionate, 6.19 g of copper (I) chloride, 12.61 g of copper (II) chloride, and 120 ml of acetonitrile at room temperature, and the mixture was stirred for 3 hours. The reaction mixture was poured into a mixture of ice and 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 13.16 g of ethyl 2-[3-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3, 6-tetrahydropyrimidin-1-yl]phenoxy}-2-pyridyloxy]propionate (compound b-10).
