Reaction Conditions

Reaction Steps

To a suspension of 2-(5-bromo-1-tert-butyl-1H-benzimidazol-2-yl)-benzonitrile (765 mg, 2.16 mmol) in EtOH (15 mL) is added hydroxylamine 50% aqueous solution (2.85 mL, 43.19 mmol) at room temperature. The solution is heated to 80° C. for 2 hours. The reaction mixture is cooled to room temperature and the ethanol removed in vacuo. Water (30 mL) is added to the reaction mixture and the resultant precipitate is filtered and washed with 10% EtOAc/heptane (10 mL) to afford 2-(5-bromo-1-tert-butyl-1H-benzimidazol-2-yl)-N-hydroxy-benzamidine (716 mg, 81%).
