Versuchsvorschrift

To the anhydrous THF solution (0.5 mL) of 9-acetyl-6,6-dimethyl-11-oxo-8-piperazin-1-yl-6,11-dihydro-5H-benzo[b]carbazole-3-carbonitrile (Compound H8-5, 25 mg, 0.06 mmol), 3-chloro-3-methyl-but-1-yne (0.013 mL, 0.12 mmol), copper (I) chloride (0.6 mg, 0.006 mmol) and triethylamine (0.017 mL, 0.12 mmol) were added at room temperature. After stirring for 30 min, the mixture was added with water and extracted with ethyl acetate. The organic layer was dried over magnesium sulfate. The drying agent was removed by filtration and the residues obtained after concentration under reduced pressure were purified by amino silica gel column chromatography (dichloromethane/methanol) to obtain the title compound (white solid, 9.8 mg, 35%).
