Procedure

To a mixture of 6.46 g of 2-(2-benzyloxyphenoxy)-5-fluoro-4-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]aniline, 2.45 g of copper chloride (I), 5.04 g of copper chloride (II) and 90 ml of acetonitrile was added dropwise 4.46 g of isoamyl nitrite at room temperature, and the mixture was stirred for 1 hour. The reaction solution was poured into 2% hydrochloric acid and extracted with ethyl acetate. The organic layer was washed with saturated aqueous sodium chloride solution, dried over anhydrous magnesium sulfate and concentrated. The obtained residue was subjected to silica-gel column chromatography to give 4.6 g of ([2-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}phenoxy]methyl)benzene.
