A synthesis of novel 4-substituted-3-cyano-2-aminopyridines using enaminonitriles and various primary amines was established under microwave irradiation and solvent-free conditions. Structures of the new compounds were characterized by IR, MS, 1H and 13C NMR data and the structure of 2-aminopyridine of the products was confirmed by X-ray analysis.
在微波辐射和无溶剂条件下,使用烯胺腈和各种伯胺合成了新型的4-取代的-3-氰基-2-氨基吡啶。通过IR,MS,1 H和13 C NMR数据表征了新化合物的结构,并且通过X射线分析证实了产物的2-氨基吡啶的结构。
