[0061]

[0062] Synthesis of Intermediate 1-1;

[0063] Under nitrogen protection, in a four-necked flask equipped with mechanical stirring, add raw materials carbazole (30g, 180mmol, 1eq), 1-(4-bromophenyl)-4-chlorobiphenyl (61.4g, 180mmol, 1eq), three (dibenzylideneacetone) dipalladium (5.0g, 5.4mmol, 3%eq), tri-tert-butylphosphine tetrafluoroborate (3.1g, 10.8mmol, 6 %eq), sodium tert-butoxide (26g, 270mmol, 1.5eq), and 300mL toluene were reacted at 80°C for 24h. After cooling down to room temperature, 250 mL of aqueous solution was added directly, the aqueous phase was extracted three times with 200 mL of dichloromethane, and the combined organic phases were concentrated to obtain a crude product. The crude product was boiled and washed in petroleum ether, and filtered to obtain 27g of white powder.
