Reaction Conditions:

with copper;potassium carbonate in N,N-dimethyl-formamide at 130;

Steps:

1.3 Synthesis of intermediate product (C)

Carbazole 2.00 g (12.0 mmol), 1-bromo-3-iodobenzene, 2.02 mL (15.8mmol), copper (Cu) 2.29 g (36.0 mmol) of calcium carbonate and 4.98 g (36.0 mmol) of DMF in 30 mL insert heated at 130 It was stirred. After the completion of the reaction, it cooled to ambient temperature and diluted with ethyl acetate to a vacuum filter, and passed through a silica gelThe filtrate was concentrated under reduced pressure. Separating the product by silica gel column chromatography (ethyl acetate: n- hexane = 1: 20) to give the desired intermediate compound (C) 3.80 g (98% yield).
