Procedure

855 mg (2.02 mmol) of ethyl 4,4,4-trifluoro-2-{4-[(4-fluoro-1-oxo-1,3-dihydro-2H-isoindol-2-yl)methyl]phenyl}-3-methylbutanoate were dissolved in 5.7 ml each of THF, methanol and water, and 16.2 ml (40.39 mmol) of 10% strength aqueous sodium hydroxide solution were added. The mixture was stirred at RT overnight. The reaction mixture was then diluted with water, acidified with 1 N hydrochloric acid and extracted with ethyl acetate. The organic phase was dried over sodium sulfate and concentrated. The crude product was purified by preparative RP-HPLC (mobile phase: acetonitrile/water gradient). This gave 457.2 mg (58.2% of theory) of the target compound.
