Synthesis of new coumarin containing benzimidazole derivatives

Abstract

This study describes the synthesis of a new series of benzimidazoles that contain a coumarin moiety. The high yielding synthetic reaction was between hydrazide derivatives of benzimidazoles and 3-(1H-benzotriazol-1-ylcarbonyl)-2H-chromen-2-one. The reaction was performed using a very small amount of the organic solvent and without the use of a catalyst.
