実験手順

Under nitrogen atmosphere, 8-((R)-2,3-dihydroxy-propoxy)-4-hydroxy-6,6-dimethyl-11-oxo-6,11-dihydro-5H-benzo[b]carbazole-3-carbonitrile (Compound U8-4-2, 8.0 mg, 20.39 μmol) was dissolved in methanol (2.0 mL) and chloroform (2.00 mL), added with trimethylsilyldiazomethane (diethyl ether solution, 2 M, 15.3 μL, 30.58 μmol) and diisopropylethylamine (0.05 mL), and then stirred at room temperature for 31 hr. The residues obtained from the reaction solution after concentration under reduced pressure were purified by silica gel column chromatography (methanol/dichloromethane) to obtain the title compound (5.1 mg, 62%).
