Mode opératoire

In a nitrogen atmosphere, an ethylene glycol dimethyl ether (20 mL) solution containing 9.5 g (29 mmol) of N,N-bis(4-bromophenyl)amine, 7.9 g (65 mmol) of phenyl boronic acid, 0.15 g (0.646 mmol) of palladium acetate, and 1.4 g (4.5 mmol) of tris(o-thryl)phosphine, to which 95 mL of a potassium carbonate solution (2.0 mol/L) is added, is rectified at 90° C. for seven hours. After completion of reaction, the reaction mixture is filtrated, and the obtained solid is recrystallized with chloroform and hexane to obtain 6.7 g (yield: 72%) of N,N-di(4-biphenylyl)amine which is an object as a white powdered solid.
