Synthesis of some novel 2-substituted-N-aryl-benzoxazole-5-carboxamides using cobalt dipyridine dichloride as a catalyst

摘要

An efficient synthesis of some novel 2-substituted-N-aryl-benzoxazole-5-carboxamides from 2-substituted -5-carbomethoxy benzoxazole on treatment with different substituted anilines promoted by cobalt dipyridine dichloride as a catalyst is described. This new approach has the advantage of excellent yields (90%) and short reaction times 1-2 h.
