实验过程

A solution of the compound (0.845 g) obtained in (1) above in methanol (20 ml) was vigorously stirred in the presence of 10% palladium-carbon (0.106 g) in a stream of hydrogen. After filtering through Celite, the mixture was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (developing solvent: hexane/ethyl acetate=4/1 v/v) to give the title compound (0.810 g, yield 95%).
