Procedure

200 mg of 2-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-3-hydroxypyridine and 80 mg of methyl 2-bromopropionate were dissolved in acetonitrile, to this was added 66 mg of potassium carbonate, and the mixture was stirred for 2 hours at 60° C. This reaction solution was poured into ice water, 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 77 mg of 2-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-3-{1-(methoxycarbonyl)ethoxy}pyridine [present compound 2-2].
