Procedure
A mixture of 0.60 g of methyl [3-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-2-pyridyloxy]acetate (compound a-6), 0.13 g of sodium carbonate, and 7.0 ml of n-propanol was stirred under reflux for 2 hours. After cooling to room temperature, the solvent was distilled out under reduced pressure, and the residue was subjected to silica gel column chromatography to give propyl [3-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-2-pyridyloxy]acetate (compound a-14).
