Eco-friendly synthesis of 2-(3H-imidazo[4,5-b]pyridin-2-yl)-N-phenylbenzamide derivatives from diethylphthalate, anilines and pyridine-2,3-diamine was described by one-pot three component method via green approaches. Phosphoric acid has been used as an effective catalyst for this kind of one-pot three component reaction. This reaction takes short time, easy workup and gives excellent yields in glycerol medium.
