To a solution of 3-propyl-5-aminobenzimidazole (0.71 g, 4.3 mmol) in 10 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/CH2Cl2) to provide 0.40 g (1.6 mmol, 37%) of the product.
