Product 1

HCID 68880940N-benzyl-3,6-di(N-carbazolyl)carbazoleYield 70%

Procedure

The obtained N-benzyl-3,6-dibromocarbazole was allowed to couple with carbazole in the same manner as described in synthesis of N-ethyl-3,6-dibromocarbazole (Embodiment 1) to give N-benzyl-3,6-di(N-carbazolyl)carbazole. The yield was 70%.
