Synthesis of Pyrido[1,2‐a]benzimidazoles through a Copper‐Catalyzed Cascade C–N Coupling Process

A simple and efficient method for the preparation ofpyrido[1,2-a]benzimidazoles by a copper-catalyzed inter- and intramolecular C–N coupling cascade process was designed and carried out, and the products were obtained in moderate to excellent yields (up to 93 %).
