실험 절차
The compound (18.0 g) obtained in Example 103-2 was dissolved in chloroform (540 ml) and then added with manganese dioxide (chemically processed product) (118 g), followed by stirring at room temperature for 15 hours. The reaction solution was filtrated through Celite and the filtrate was then concentrated under reduced pressure. The residue was purified through silica gel column chromatography (chloroform/ethyl acetate), thereby obtaining the subject compound (17.1 g) as a white solid.
