At 0° C., 222.6 mg (1.67 mmol) of 2,3-dihydro-1H-isoindol-1-one were added to 66.9 mg (1.67 mmol, 60% pure) of sodium hydride in 2 ml of DMF. The mixture was stirred for 30 min, and 600 mg (1.39 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 preparative RP-HPLC (mobile phase: acetonitrile/water gradient). This gave 108 mg (19% of theory) of the target compound.
