실험 절차

To a mixture of 1.3 g of sodium hydride and 100 ml of dimethoxyethane, 10 g of 2-chloro-4-fluoro-5-(3-methyl-2,6-dioxo-4-trifluoromethyl-1,2,3,6-tetrahydropyrimidin-1-yl)phenol were added at room temperature and stirred for 30 minutes. Then, 2.2 g of sodium iodide and 6.7 g of crude 2-chloro-2-(methylthio)acetamide were added thereto and stirred at room temperature for 3 hours, and water was poured into the reaction mixture. The reaction mixture was extracted with ethyl acetate. The organic layer was washed with aqueous sodium bicarbonate solution, dried over anhydrous magnesium sulfate and concentrated. The residue was subjected to silica gel column chromatography (eluent: ethyl acetate) to give 10.2 g of 2-[2-chloro-4-fluoro-5-(3-methyl-2,6-dioxo-4-trifluoromethyl-1,2,3,6-tetrahydropyrimidin-1-yl)phenoxy]-2-(methylthio)acetamide.
