Versuchsvorschrift

The compound (595 mg, 0.901 mmol) obtained in Example 68b was dissolved in tetrahydrofuran (12 mL), a 1 N aqueous sodium hydroxide solution (1.03 mL, 1.03 mmol), water (0.3 mL) and methanol (4 drops) were added, and the mixture was stirred at room temperature. After the reaction was completed, 1 N hydrochloric acid and water were added, the mixture was extracted with methylene chloride, and the resulting organic layer was dried with anhydrous sodium sulfate. The solvent was evaporated under reduced pressure, and the resulting residue was purified by reverse phase liquid chromatography (XTerra Prep MS C18 OBD, 5 μm, 30×100 mm) (acetonitrile:0.1% aqueous ammonium acetate solution, 10:90→100:0, v/v) to give the title compound (233 mg; yield, 40%).
