In this paper, 9-Ethyl-3,6-di-pyridin-4-yl-9H-Carbazole was synthesized by the method of Suzuki cou-pling reaction with carbazole as raw materials. Firstly, N-ethyl carbazole was generated by the substitution reaction of Carbazole with bromine ethane, Then the obtained product reacted with N-bromosuccinimide and generated 3,6-dibromo-N-ethyl carbazole. Finally the target compound was obtained by Suzuki coupling reaction of 3,6-dibromo-N-ethyl carbazole with pyridine-4-boric acid. The total yield was 55. 7%, and the target compound was character-ized with 1 H NMR.
