Versuchsvorschrift
Compound 44 (145 mg, 0.400 mmol) was dissolved in pyridine (5 mL), acetic anhydride (0.19 mL, 2.00 mmol) was added thereto, followed by stirring at room temperature for 2 hours. The reaction mixture was concentrated under reduced pressure, and the resulting residue was purified through silica gel column chromatography (ethyl acetate:methanol=9:1) to afford the entitled Compound 54 (40.0 mg, 25%).
