The compound (81.9 mg) obtained in Example 52-3 was dissolved in THF (2.0 ml) and added with triethylamine (76.0 μl) and methyl bromoacetate (46.0 μl) and the whole was stirred at room temperature for 11 hours under a nitrogen atmosphere. After completion of the reaction, the solution was added with methanol and the solvent was distilled off under reduced pressure. The residue was purified through silica gel column chromatography (chloroform/methanol), thereby obtaining the subject compound (23.7 mg) as a yellow oily substance.
