Vorschrift

A mixture of 0.60 g of 3-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-2-(methoxycarbonyl)methoxypyridine [present compound 7-7], 0.13 g of sodium carbonate and 7.0 ml of n-propanol was refluxed for 2 hours. It was cooled to room temperature, then, the solvent was distilled off under reduced pressure, and the resulted residue was subjected to silica gel chromatography to obtain 0.62 g of 3-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-2-(n-propoxycarbonyl)methoxypyridine [present compound 7-48].
