3-Chloro-9-bromo-8-((S)-2,2-dimethyl-[1,3]dioxolan-4-yl methoxy)-6,6-dimethyl-5,6-dihydro-benzo[b]carbazol-11-one (Compound S7-2, 17 mg, 37 mmol) was dissolved in DMA, added with CuCN (17 mg, 5 eq.), and stirred at 220° C. for 2 hr under irradiation with microwave. After cooling, the reaction solution was added with ethyl acetate, and the precipitated solid was filtered to remove the solvent. The resulting residues were purified by HPLC to obtain the title compound (4 mg).
