実験手順

To a mixed suspension of the compound (2.53 g) obtained in Example 6 in ethanol (200 mL)/ethyl acetate (100 mL) was added 10% palladium/carbon (500 mg), and the mixture was heated under reflux under hydrogen atmosphere for 6 hr. After allowing to cool to room temperature, insoluble material was removed by filtration, and the filtrate was concentrated under reduced pressure to give the title compound (2.37 g) as a white powder. In some cases, the compound was further converted to a hydrochloride salt with 4 mol/L hydrochloric acid/ethyl acetate and used.
