A novel and efficient four-component approach for the synthesis of 2,3-disubstituted imidazo[1,2-a]pyridines is described. The copper-catalyzed reductive amination of 2-bromopyridine by sodium azide followed by sequential condensation and cyclization with aldehydes and isocyanides afforded the corresponding imidazo[1,2-a]pyridines in good yields.
