PROCEDURE

实验过程

Compound (41) (18 mg) obtained in item (8) above was dissolved in a 0.1M sodium methylate solution (0.72 ml) in methanol, and the resultant solution was allowed to stand at room temperature overnight. The reaction solution as formed was neutralized with addition of dry ice and then concentrated to leave a residue. The residue was purified by silica gel column chromatography (developer: the lower layer of water-methanol-chloroform, 1:2:4), affording the titled compound (42) (4.7 mg) as a colorless solid. Yield: 30%.
