Water → 2-(3,5-Dibromophenyl)-1-phenyl-1h-benzo[d]imidazole

Participants

Reaction Steps

20 g (75.8 mmol) of 3,5-dibromobenzaldehyde and 16.8 g (90.9 mmol) of N-phenyl-o-phenylenediamine were dissolved in 150 mL of acetic acid. The solution was agitated at room temperature for 30 minutes. Next, 37 g (83.4 mmol) of lead(IV) acetate was added thereto. The resulting product was agitated at 50° C. for 1 hour. Then, water was poured into the obtained reactant. The resulting product was treated with ethyl acetate to perform extraction and the solvent was removed under a reduced pressure. The extract was separated through a column and dried, obtaining 9.5 g (Y=29%) of a yellow solid.
