Under nitrogen atmosphere, 4-bromo-8-((S)-2,2-dimethyl-[1,3]dioxolan-4-yl methoxy)-6,6-dimethyl-11-oxo-6,11-dihydro-5H-benzo[b]carbazole-3-carbonitrile (Compound U8-1, 30.0 mg, 60.56 μmol), palladium acetate (1.36 mg, 6.056 μmol), 1,1′-bis(diphenylphosphino)ferrocene (3.36 mg, 6.056 μmol), imidazole (4.12 mg, 60.56 μmol) and tert-potassium butoxy (10.2 mg, 90.84 μmol) were dissolved in formamide (3.00 mL) and the mixture was stirred at 180° C. for 5 min under irradiation with microwave. The reaction solution was poured into water, extracted with ethyl acetate, washed with water and saturated brine, dried over sodium sulfate, and then filtered. The residues obtained after concentration under reduced pressure were purified by silica gel column chromatography (methanol/dichloromethane) to obtain the target compound (7.6 mg, 27%).
