Procedure

1,4-bis(4-aminophenyl)-2,3,5,6-tetraphenylbenzene was prepared according to the procedure set forth in Example 2 with 1,4-bis(4-nitrophenyl)-2,3,5,6-tetraphenylbenzene being used at the same molar amount as 1,4-bis(4-nitrophenyl)-2,3,5-triphenylbenzene in Example 3, but the yield was only 45%. The crude product was recrystallized from pyridine.
