Versuchsvorschrift

Compound 39b (1.0 g) was added to methanol (10 mL), and 4M aqueous sodium hydroxide (650 μL) and water (400 μL) were further added thereto, followed by stirring at room temperature for 2 hours. After completion of reaction, 6N aqueous hydrochloric acid was added to the reaction mixture, to thereby adjust the pH to 3, and the precipitate was filtrated, whereby compound 39c was yielded (862 mg, yield: 90%).
