Abstract

An efficient method has been developed for the synthesis of 4, 6-dimethylpyridine-2, 3- dicarbonitrile. A study was carried out on the reaction of this compound with N- acylhydrazines to give two structural isomers, namely, N′-(7-amino-2, 4-dimethyl-5 H- pyrrolo [3, 4-b] pyridin-5-ylidene) carbohydrazides and N′-(5-amino-2, 4-dimethyl-7 H- pyrrolo [3, 4-b] pyridin-7-ylidene) carbohydrazides as well as disubstituted N′, N ″-(2, 4- ...
