Procedure

6-(10-phenylanthracen-9-yl)-9H-pyrido[2,3-b]indole (1.76 g, 4.19 mmol), 1,4-diiodobenzene (2.76 g, 8.37 mmol), CuI (319 mg, 1.67 mmol), K3PO4 (1.78 g, 8.37 mmol), trans-1,2-dicyclohexanediamine (0.2 mL, 1.67 mmol) were put in a 250 mL two-neck flask and dissolved in 1,4-dioxane. The solution was refluxed and stirred at 120° C. for 12 hours. After completion of the reaction, the solution was extracted with methylenechloride/H2O and distilled under reduced pressure to remove the solvent. The resultant was columned with a solution of n-hexane and methylenechloride (1:5) and was re-crystallized in a solution of methylene chloride and petroleum ether such that the solid compound was obtained, (1.67 g, yield: 64%).
