Reaction Steps

2-(3-Bromophenyl)-1-phenyl-1H-benzo[d]imidazole (m-BPBI) was prepared as the same procedure as 2-(4-bromophenyl)-1-phenyl-1H-benzo[d]imidazole from N-phenyl-o-phenylenediamine and 4-bromobenzaldehyde. The isolated yield of the compound was 85%. It has the same spectroscopic data as that as the bona fide compound.11
