Reaction Steps

The compound (182.6 mg) obtained in Example 21-4 was dissolved in chloroform (7.0 ml) and added with triethylamine (0.133 ml) and acetic anhydride (73.5 mg) and the whole was stirred at room temperature for 24 hours. The reaction solution was added with water, subjected to extraction with chloroform, dried with anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was purified through silica gel column chromatography (chloroform/ethyl acetate), thereby obtaining the subject compound (253.2 mg) as a colorless oily substance.
