The compound (439 mg) obtained in Example 121-10 was dissolved in a 40% methylamine/methanol solution (45 ml) and stirred at room temperature for 3 days. After completion of the reaction, the solvent was distilled off. Then, a 1 mol/l sodium hydroxide aqueous solution was added to the residue, and the whole was stirred. The solution was extracted with chloroform and the extract was washed with saturated saline solution. After that, the organic layer was dried with anhydrous sodium sulfate. Then, the solvent was distilled off, thereby obtaining the subject compound (283 mg) as a colorless oily substance.
