Reaction Steps

A mixture of 3,4-diaminobenzonitrile (3.0 g, 0.023 mol) and the imidate in 500 mL of methanol was heated at 70° C. under nitrogen. The reaction was followed by TLC with 1:1 Hex/EtOAc. After 4 h the reaction solution was place under vac cuo to remove all solvents. The residue was recrystallized from ethyl acetate to afford 4.5 g (85%) of 2-(4-hydroxyphenyl)-1H-benzimidazole-5-nitrile.
