Reaction Steps

To a solution of ethyl 3-(6-fluoropyridin-3-yl)-3-oxopropionate (3.83 g, 18.1 mmol) in 1,2-dimethoxyethane (30 ml) was added sodium hydride (60% in oil, 725 mg, 18.1 mmol) under ice-cooling, and the mixture was stirred at room temperature for 30 min. To the reaction solution was dropwise added 3-(1,1,2,2-tetrafluoroethoxy)-α-bromotoluene (9.30 g, purity 56%, 18.1 mmol) in 1,2-dimethoxyethane (10 ml), and the mixture was stirred at room temperature for 2 hrs. The reaction solution was poured into water (100 ml), and the mixture was extracted with ethyl acetate (100 ml×2). The extract was washed with water and saturated brine, dried over anhydrous magnesium sulfate and evaporated under reduced pressure. The residue was purified by silica gel column chromatography (toluene-toluene:ethyl acetate=5:1) to give ethyl 3-(6-fluoropyridin-3-yl)-3-oxo-2-((3-(1,1,2,2-tetrafluoroethoxy)phenyl)methyl)propionate (6.67 g, 88%) as a colorless oil.
