Methyl iodide → 3-[2-Chloro-4-fluoro-5-(3-methyl-2,6-dioxo-4-trifluoromethyl-1,2,3,6-tetrahydropyrimidin-1-yl)phenoxy]-2-(methoxycarbonylmethoxy)pyridine

Participants

Reaction Steps

To a mixture of 0.10 g of 3-{2-chloro-4-fluoro-5-[2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-2-(methoxycarbonyl)methoxypyridine, 1 ml of acetonitrile and 31 mg of potassium carbonate, 32 mg of methyl iodide was added to the mixture, and the mixture was stirred at room temperature for 1.5 hours. 64 mg of methyl iodide was added to the mixture, and the mixture was stirred at 50° C. for 1 hour. The mixture was filterated, and the filterate was concentrated under reduced pressure. The residue was subjected to silica gel column chromatography to obtain 97 mg 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].
