Reaction Steps

To a solution of 3-benzyl-5-aminobenzimidazole (0.88 g, 3.9 mmol) in 20 ml of AcOH was added solution of Br2 in AcOH until it produces a precipitation. The reaction mixture was concentrated in vacuo to provide a brown solid which was subjected to column chromatography (5% NH3 sat'd MeOH/CHCl3) to provide 0.35 g (1.2 mmol, 29%) of the product.
