Reaction Steps

To a solution of 3-cyclopentyl-5-aminobenzimidazole (1.0 g, 5.0 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 0.70 g (2.5 mmol, 50%) of the product.
