実験手順

Under argon, 270 mg (0.66 mmol) of ethyl 4,4,4-trifluoro-3-methyl-2-{4-[(1-oxo-1,3-dihydro-2H-isoindol-2-yl)methyl]phenyl}butanoate were dissolved in 1 ml each of THF, methanol and water, and 69.9 mg (1.66 mmol) of lithium hydroxide were added. The mixture was stirred at RT overnight. The reaction mixture was diluted with water and acidified with 1 N hydrochloric acid, and the resulting precipitate was filtered off with suction. The solid was washed with water until the washings remained neutral. This gave 222 mg (88.3% of theory) of the target compound.
