Participants

Reaction Steps

According to the same manner as that described in Synthesis Example 1, 16.19 of N,N'-diacetyl-2,5,2',5'-tetramethylbenzidine was reacted with 21.8 g of 4-methyliodobenzene to give N,N'-bis(4-methylphenyl)-2,5,2',5'-tetramethylbenzidine. Further, 12.0 g of N,N'-bis(4-methylphenyl)-2,5,2',5'-tetramethylbenzidine was reacted with 13.0 g of 4-tert-butyliodobenzene according to the same manner as that described in Synthesis Example 1 to give N,N'-bis(4-methylphenyl)-N,N'-bis(4-tert-butylphenyl)-2,5,2',5'-tetramethylbenzidine of the formula (4-a) (9.0 g, yield: 27.1%).
