Reaction Conditions

Reaction Steps

85 g (350 mmol) of 3-phenyl-9H-carbazole, 63 ml (262 mmol) of methyl 2-iodobenzoate, 20 g (315 mmol) of copper powder, 87 g (631 mmol) of potassium carbonate and 9.3 g (35 mmol) of 18-crown-6 are initially introduced in 1200 ml of DMF under a protective gas and heated at 1300° C. for 86 h. The mixture is subsequently evaporated and washed by stirring with hot heptane and purified by chromatography (heptane, dichloromethane 1:1). The product is washed by stirring with hot hexane, and the solid is isolated.
