Procedure

60 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 20 mg of methyl bromoacetate were dissolved in 2 ml of acetonitrile, to this was added 20 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 60 mg of 2-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-3-(methoxycarbonyl)methoxypyridine [present compound 2-7].
