Reaction Steps

The compound (180 mg, 0.12 mmol) obtained in Example 97f was dissolved in a mixed solvent of ethanol (3 mL) and ethyl acetate (3 mL), 10% palladium-carbon (36 mg, 20% by weight) was added, and the mixture was stirred at room temperature under a hydrogen atmosphere for 18 hours. After the reaction was completed, the reaction mixture was filtered through celite, the filtrate was washed with methanol, and the solvent was evaporated under reduced pressure. The residue was purified by NH silica gel column chromatography (ethyl acetate:methanol, 30:1, v/v) to give the title compound (141 mg; yield, 86%) as a white solid.
