The compound (66.2 mg) obtained in Example 49-1 was dissolved in anhydrous chloroform (2.7 ml). Then, the solution was added with triethylamine (0.028 ml) and then added with methyl chloroformate (manufactured by Kanto Kagaku) (0.015 ml), followed by stirring at room temperature for 6 hours. After completion of the reaction, the solution was added with chloroform (3.0 ml), followed by washing with water and a saturated aqueous sodium bicarbonate solution. The organic layer was dried with anhydrous magnesium sulfate and the solvent was then distilled off, thereby obtaining the subject compound (65.2 mg) as a yellow viscous solid.
