3-Bromo-8-((S)-2,2-dimethyl-[1,3]dioxolan-4-yl methoxy)-6,6-dimethyl-5,6-dihydro-benzo[b]carbazol-11-one (20.0 mg, 0.043 mmol), thiophene-3-boronic acid (10.9 mg, 0.085 mmol), K3PO4 (40 mg) and Pd (PPh3)4 (9.9 mg, 0.0086 mmol) were dissolved in DMA (0.8 ml) and water (0.2 ml), and stirred at 140° C. for 10 min under microwave irradiation. The reaction solution was diluted with ethyl acetate and washed with saturated brine. The organic layer was concentrated under reduced pressure, and the resulting residues were purified by column chromatography (hexane/ethyl acetate) to obtain 8-((S)-2,2-dimethyl-[1,3]dioxolan-4-yl methoxy)-6,6-dimethyl-3-thiphen-3-yl-5,6-dihydro-benzo[b]carbazol-11-one.
