실험 절차
A solution of the compound (190 mg) obtained in Example 33 in 4.4% formic acid-methanol (10 ml) was added dropwise to a suspension of palladium-black (200 mg) in 4.4% formic acid-methanol (10 ml) at room temperature and stirred at room temperature for 16 h. The reaction mixture was filtered and the filtrate was concentrated under reduced pressure; the resulting residue was purified by silica gel column chromatography (eluent, chloroform methanol=8:2) to give 71 mg of the titled compound (yield, 37%).
