실험 절차

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 5-fluoro-2-{2-(methoxycarbonyl)methoxyphenoxy}-4-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]aniline (produced in Intermediate Production Example 10), 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 hour. 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 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 3-11 of the present invention].
