Versuchsvorschrift

THF/methanol (1/1, 60 ml) and 0.25N NaOH (43 ml, 10.6 mmol) were added to ethyl (5-chloro-2-fluoro-4-(((5-fluoro-1-methyl-3-indolyl)carbonyl)amino)phenyl)acetate (865 mmol, 2.13 mmol) and the mixture was stirred at room temperature for 3 hours. The reaction mixture was poured in 1N HCl, followed by extraction with a chloroform/methanol (10/1) mixture. The extract was dried over anhydrous sodium sulfate, and distilled under reduced pressure to remove the solvent. The residue was solidified with methanol/chloroform/hexane. The crystals thus precipitated were collected by filtration under reduced pressure and dried under reduced pressure to give (5-chloro-2-fluoro-4-(((5-fluoro-1-methyl-3-indolyl)carbonyl)amino)phenyl)acetic acid (736 mg, 91%) as a white crystalline powder.
