Procedure
To a solution of ethyl 3-oxo-3-(4-phenoxyphenyl)propionate (12 g, 42.2 mmol) in 1,2-dimethoxyethane (80 ml) was added sodium hydride (60% in oil, 1.69 g, 42.2 mmol) under ice-cooling, and the mixture was stirred at room temperature for 30 min. To the reaction solution was dropwise added a solution of 4-trifluoromethylbenzyl bromide (10.1 g, 42.2 mmol) in 1,2-dimethoxyethane (50 ml), and the reaction solution was stirred at room temperature for 4 hrs. The reaction solution was poured into water (200 ml), and extracted with ethyl acetate (200 ml×2). The extract was washed with water and saturated brine, dried over anhydrous magnesium sulfate and evaporated under reduced pressure. The residue was recrystallized from ethyl acetate-hexane to give ethyl 3-oxo-3-(4-phenoxyphenyl)-2-((4-(trifluoromethyl)phenyl)methyl)propionate (14.0 g, 75%).
