Procedure

To a mixture of 50 mg of 6-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-2-pyridone, 21 mg of methyl 2-bromopropionate and 1 ml of N,N-dimethylformamide was added 21 mg of potassium carbonate, and the mixture was stirred for 1 hour at 50° C. The solution was cooled to room temperature, poured into 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 72 mg of 2-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-6-{1-(methoxycarbonyl)ethoxy}pyridine [present compound 2-42].
