Procedure
To a solution of 1-cyclopentyl-5-aminobenzimidazole (1.1 g, 5.5 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/CH2Cl2) to provide 0.54 g (1.9 mmol, 35%) of the product.
