실험 절차

The compound (883 mg) obtained in Example 29-2 was dissolved in methanol (18 ml) and added with a 1 mol/l sodium hydroxide aqueous solution (9.0 ml) and the whole was stirred overnight at room temperature. After completion of the reaction, the solvent was distilled off under reduced pressure. The residue was dissolved in 1 mol/l hydrochloric acid, subjected to extraction with chloroform, and dried with anhydrous sodium sulfate. After filtration, the solvent was distilled off and the residue was dried under vacuum, thereby obtaining the subject compound (820 mg) as a white solid.
