Procedure

Intermediate 74 (746 mg) obtained in Example 105, Step B was added with acetic acid (1.5 ml) and 30% aqueous hydrogen peroxide (2 ml) and stirred at room temperature for 17 hours. The reaction mixture was added with ethyl acetate (50 ml) and washed three times with saturated aqueous sodium hydrogencarbonate (25 ml for each time), and the organic layer was dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (n-hexane:acetone=3:1) to obtain the title compound (390 mg).
