PROCEDURE

实验过程

The compound (95.0 mg) obtained in Example 49-1 was dissolved in pyridine (5.0 ml) and added with N,N-dimethylcarbamoyl chloride (20.0 mg). After the solution had been stirred at room temperature for 15 hours, pyridine was distilled off and the residue was then added with a saturated aqueous sodium bicarbonate solution and extracted with chloroform. The extract was concentrated and purified through column chromatography (chloroform/methanol), thereby obtaining the subject compound (45.4 mg) as a white solid.
