Eco-friendly, one-pot three-component syntheses of 2-(3H-imidazo[4,5-b]pyridine-2-yl)-N-arylbenzamides have been developed by combining phthalic anhydride with anilines and pyridine-2,3-diamine in water without any catalyst. These reactions involves easy workup, provide good yields and use of water as solvent which were the merits of this preparation.
通过将邻苯二甲酸酐与苯胺和吡啶-2,3结合使用,开发出了一种环保型一锅三组分合成2-(3H-咪唑并[4,5-b]吡啶-2-基)-N-芳基苯甲酰胺的方法。 -二胺在水中,无需任何催化剂。这些反应涉及容易的后处理,提供良好的收率和使用水作为溶剂,这是该制备的优点。
