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