At 0° C., 645 mg (4.27 mmol) of 4-fluoro-2,3-dihydro-1H-isoindol-1-one were added to 170.7 mg (4.27 mmol, 60% pure) of sodium hydride in 4 ml of DMF. The mixture was stirred for 30 min, and 2.11 g (5.98 mmol) of ethyl 2-[4-(bromomethyl)phenyl]-4,4,4-trifluoro-3-methylbutanoate were then added at 0° C. The reaction mixture was stirred for a further 2 h, and water and ethyl acetate were then added. 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 40:1 to 3:1). This gave 856 mg (33.9% of theory) of the target compound.
