A solution (2 ml) of Intermediate 81 (103 mg) in methanol was vigorously stirred in the presence of 10% palladium carbon catalyst (16.5 mg) at room temperature under hydrogen atmosphere of ordinary pressure. The reaction mixture was filtered through Celite, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=2:1) to obtain the title compound (93.7 mg).
