Reaction Steps

To a round bottom flask is added 2-(5-bromo-1-tert-butyl-1H-benzimidazol-2-yl)-benzamide (400 mg, 1.075 mmol) in N,N-dimethylformamide dimethyl acetal (8 mL). The reaction mixture is stirred at 110° C. for 3 hours. The reaction mixture is concentrated to remove all volatile material to afford 2-(5-bromo-1-tert-butyl-1H-benzimidazol-2-yl)-N-[1-dimethylamino-meth-(E)-ylidene]-benzamide (460 mg, 100%) ready for the next step. LCMS (ESMS): m/z 427.68, 429.64 (M++1)
