[3-Bromo-6,6-dimethyl-11-oxo-8-((2R,3R)-2,3,4-trihydroxy-butoxy)-6,11-dihydro-benzo[b]carbazol-5-yl]-acetic acid (Compound T22-6, 15.0 mg, 29.0 μmol) was dissolved in methanol (0.30 mL), added with trimethylsilyldiazomethane (0.10 mL), and then stirred at room temperature for 1 hr. The residues obtained from the reaction solution after concentration under reduced pressure were purified by silica gel column chromatography (methylene chloride/methanol) to obtain the target compound (15.2 mg, 96%).
