실험 절차

The compound (90 mg) obtained in Example 40 was dissolved in N,N-dimethylformamide (3 mL), triethylamine (65 μl) and acetic anhydride (22 μl) were added, and the mixture was stirred overnight at room temperature. The reaction mixture was concentrated under reduced pressure, and methylene chloride and 0.3N aqueous sodium hydroxide were added to the residue for partitioning the mixture. The resultant organic layer was dried over sodium sulfate anhydrate. The solvent was distilled away under reduced pressure, and the residue was purified by silica gel column chromatography (methylene chloride:methanol=100:3) to give a colorless foamy substance. This product was suspended in 1N hydrochloric acid (0.3 mL), and the suspension was concentrated under reduced pressure to give the title compound (73 mg).
