실험 절차
The compound prepared in Example 81 (4.40 g) was dissolved in benzene (500 mL)-ethanol (50 mL) and 1 mol/L aqueous sodium hydroxide (67.0 mL) was added. This mixture was cooled to 0° C. Oxygen was bubbled through the vigorously stirred mixture for 30 minutes. The mixture was separated and the aqueous portion was extracted with dichloromethane. The combined organics were washed with brine, dried over anhydrous magnesium sulfate and concentrated. The residue was purified by column chromatography on silica gel (hexane:ethyl acetate=4:1) to obtain the title compound (2.53 g) having the following physical data.
