実験手順

There were mixed 20.70 g (0.050 mole) of N-(4′-iodobiphenylyl)acetanilide, 19.95 g (0.060 mole) of N,N-bis(biphenyl-4-yl)amine, 10.40 g (0.075 mole) of anhydrous potassium carbonate, 0.20 g (0.003 mole) of copper powder and 10 ml of n-dodecane, followed by reaction at 200 to 212° C. for 15 hours. The reaction product was extracted with 200 ml of toluene, and the insoluble matter was removed by filtration. Then, the filtrate was concentrated to obtain crude crystals. The crude crystals were dissolved in 80 ml of isoamyl alcohol, and 5 ml of water and 5.00 g (0.075 mole) of 85% potassium hydroxide were added, followed by hydrolysis at 130° C. After isoamyl alcohol was removed by steam distillation, extraction with 250 ml of toluene was performed, and the organic layer was washed with water, dried and concentrated. The concentrate was purified by column chromatography (carrier: silica gel, eluate: toluene/n-hexane=1/2) to obtain 24.2 g (yield: 69.9%, HPLC purity: 98.0%) of N,N-bis(biphenyl-4-yl)-N′-phenyl-4,4′-diaminobiphenyl. The melting point was 145.8 to 146.0° C.
