Procedure

To a solution of 4-(3-cyano-5,6-difluoroindol-1-yl)-2-hydroxybenzoic acid ethyl ester (0.074 g) in a mixed solvent of tetrahydrofuran (3.0 mL) and ethanol (0.75 mL) were added 0.1 g/mL aqueous lithium hydroxide solution (0.62 mL) and water (1.0 mL), and this mixture was stirred at room temperature for 26 hours. To this reaction mixture was added 2 mol/L hydrochloric acid (5 mL), this organic solvent was removed under reduced pressure. This resulting mixture was extracted with ethyl acetate, this organic layer was washed with water, and dried over anhydrous magnesium sulfate. The solvent was concentrated under reduced pressure to give the title compounds (0.06 g).
