실험 절차

1.80 g (11.04 mmol) of 5-(trifluoromethyl)pyridin-2(1H)-one were initially charged in 2.5 ml of DMF, and 0.44 g (11.04 mmol, 60% pure) of sodium hydride was added. The mixture was stirred for 30 min, and 3.0 g (8.49 mmol) of ethyl 2-[4-(bromomethyl)phenyl]-4,4,4-trifluoro-3-methylbutanoate were then added. After a further 2 h at RT, water was added and the reaction mixture was extracted with ethyl acetate. The organic phase was washed with saturated sodium chloride solution and dried over magnesium sulfate. The crude product was purified by chromatography on silica gel (mobile phase cyclohexane/ethyl acetate 10:1 to 4:1). This gave 2.89 g (78.2% of theory) of the target compound.
