Procedure

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 a 0.3N aqueous solution of sodium hydroxide were added to the residue to conduct liquid separation. The resultant organic layer was dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure, and the residue was purified by column chromatography on silica gel (methylene chloride:methanol=100:3) to obtain a colorless foamy substance. This product was suspended in 1N hydrochloric acid (0.3 ml), and the suspension was concentrated under reduced pressure to obtain the title compound (73 mg).
