Procedure

To a stirred suspension of 4-iodo-N1-(3-methoxy-4-((4-methoxybenzyl)oxy)benzyl)benzene-1,2-diamine (8.32 g, 16.97 mmol) in dichloromethane (100 mL) and methanol (50 mL) was added cyanogen bromide solution (5.0 M in acetonitrile, 17.0 mL, 85.00 mmol). The resulting brown reaction mixture was allowed to stir at room temperature. After 16 h, the mixture was treated with 1 N sodium hydroxide solution (250 mL) and was allowed to stir at room temperature. After 15 min, a precipitate formed. The solids were isolated by filtration, washed with water, and dried to afford 4.42 g (51%) of 5-iodo-1-(3-methoxy-4-((4-methoxybenzyl)oxy)benzyl)-1H-benzo[d]imidazol-2-amine as a tan solid.
