Opianic Acid in the Synthesis of Benzimidazole Derivatives

Heating an equimolar mixture of opianic acid and o-phenylenediamine in MeOH or EtOH produced 2-(2-carboxy-3,4-dimethoxyphenyl)benzimidazole, which was readily dehydrated in refluxing acetic or propionic anhydride to 11H-1,2-dimethoxyisoindolo[2,3-a]benzimidazol-11-one. Analogous reactions were carri...
