Reaction Steps

Compound 55 (44 mg, 0.15 mmol) obtained in Example 55 was dissolved in methanol (10 mL), and 10% palladium-carbon (50% wet., 40 mg) was added thereto and stirred under hydrogen pressure (0.3 MPa) at room temperature for 8 hours. The reaction mixture was filtered, and the filtrate was concentrated under reduced pressure, purified through preparative thin-layer chromatography (methanol/chloroform 1/9) and crystallized (ethyl acetate/n-hexane=1/4) to obtain Compound 56 (31 mg, 74%).
