To a 20 mL two-necked flask with a reflux condenser and a rubber cap are added 2-aminobiphenyls (0.5 mmol), [Cp*IrCl2]2 (0.01 mmol, 8.0 mg), Cu(OAc)2 (0.1 mmol, 18 mg), pivalic acid (1 mmol, 102 mg), 1-methylnaphthalene (ca. 30 mg) as an internal standard, and N-methyl-2-pyrrolidone (NMP, 3 mL). Then, the resulting mixture is stirred under air at 120 °C for 3-6 h. After cooling, the reaction mixture is extracted with ethyl acetate (100 mL). The organic layer is washed by aqueous NaHCO3 (100 mL×3), and dried over Na2SO4. After evaporation of the solvents under vacuum, the product is isolated by column chromatography on silica gel using hexane-ethyl acetate (10:1) as the eluent.
