Procedure

20.3 g (0.12 mol) of diphenylamine, 65.1 g (0.15 mol) of 3,3'-dimethyl-4,4'-diiodobiphenyl, 19.3 g (0.14 mol) of anhydrous potassium carbonate, 1.52 g (0.024 mol) of copper powder, and 20 ml of nitrobenzene were mixed. The reaction mixture was then allowed to undergo reaction at a temperature of 190° C. to 205° C. for 21 hours. The reaction product was then extracted with 200 ml of toluene. The insoluble contents were removed by filtration. The filtrate was then concentrated to dryness. The concentrate was then purified by column chromatography (carrier: silica gel; elute: 2/7 mixture of toluene and n-hexane) to obtain 32.6 g (yield: 57.2%) of N-(3,3'-dimethyl-4'-iodo-4-biphenylyl)-N,N-diphenylamine.
