実験手順

9-Bromo-8-methoxy-6,6-dimethyl-11-oxo-6,11-dihydro-5H-benzo[b]carbazole-3-carbonitrile (Compound E3-1-1, 50 mg, 0.13 mmol), bis(acetonitrile)dichloropalladium (II) (1.64 mg, 0.05 eq.), XPhos (9.05 mg, 0.15 eq.), cesium carbonate (185 mg, 4.5 eq.) and 3-methyl-1-butyn-1-ol (18.6 μl, 1.5 eq.) were dissolved in acetonitrile and stirred at 85° C. for 2 hr. The reaction solution was added to water, and then extracted with ethyl acetate. The organic layer was washed with brine and dried over sodium sulfate. The drying agent was removed by filtration and the residues obtained after concentration under reduced pressure were purified by HPLC to obtain the title compound (brown solid, 21.3 mg, 42%).
