The compound (574.4 mg) obtained in Example 119-6 was dissolved in ethanol (20 ml) and chloroform (10 ml). Then, the solution was added with 20% palladium hydroxide-carbon (172.3 mg) and then stirred at room temperature for 16 hours under a hydrogen atmosphere. After the reaction, the solution was filtrated through Celite and the solvent was then distilled off under reduced pressure. The residue was purified through silica gel column chromatography (hexane/ethyl acetate), thereby obtaining the subject compound (101.9 mg) as a yellow solid.
