[0062] Synthesis of Intermediate 1-1;
[0063] Under the protection of nitrogen, add the raw material carbazole (30g, 180mmol, 1eq), 1-(4-bromophenyl)-4-chlorobiphenyl into a 500mL four-neck flask equipped with mechanical stirring and a 500mL four-neck flask with condenser. (61.4g, 180mmol, 1eq), tris(dibenzylidene indeneacetone) dipalladium (5.0g, 5.4mmol, 3%eq), tri-tert-butylphosphine tetrafluoroborate (3.1g, 10.8mmol, 6 %Eq), sodium tert-butoxide (26g, 270mmol, 1.5eq), 300mL of toluene at 80°C for 24h. After cooling to room temperature, 250 mL of water was added directly, the aqueous phase was extracted three times with 200 mL of dichloromethane, and the organic phases were combined and concentrated to obtain a crude product. The crude product was boiled and washed in petroleum ether and filtered to obtain 27 g of white powder.
