反応手順
4,4′-dibromo-2,2′-diaminobiphenyl (3.5 g, 10.23 mmol) was dissolved in phosphoric acid and heated at 190° C. for 24 hours. The reaction mixture was cooled to room temperature and then NaHCO3 (aq) was gradually added thereto to form a solid. Then, the solid was filtered to obtain 2,7-dibromocarbazole (2.2 g, 66%), the compound represented by formula e. MS [M+] 323.
