Versuchsvorschrift

To a solution of Compound (61) (224 mg, 0.40 mmol) in 50 ml of methanol containing 1% water was added 180 mg of 10% palladium-carbon, followed by catalytic reduction. After the palladium-carbon was removed by filtration, the filtrate was concentrated under reduced pressure. The residue was purified by a silica gel column chromatography (silica gel 10 g; ethyl acetate:methanol=99:1) and further crystallization from diethyl ether-n-hexane to give 152 mg (79%) of Compound (51f).
