PROCEDURE

实验过程

To a solution of Compound (39a) (Step-1 in Example 44) (303 mg, 0.53 mmol) in 10 ml of methanol containing 1% water was added 30 mg of 10% palladium-carbon, followed by catalytic reduction under atomospheric pressure for 2.5 hours. After the catalyst was removed by filtration, the filtrate was concentrated under reduced pressure. The residue was purified by a column chromatography (silica gel 5 g; ethyl acetate) to give 234 mg (91%) of Compound (55a).
