1, 2, 4-triazole, carbethoxyformimidate, acylamidrazone, cyclocondensation, acylhydrazideAbstract
Easily accessible carboxylic acid hydrazides undergo cyclocondensation with ethyl carbethoxyformimidate, giving 5-substituted ethyl 1,2,4-triazole-3-carboxylates. These are important building blocks in organic synthesis. The approach we used to obtain title compounds made possible synthesis of 3-(2-aminophenyl)-1,2,4-triazole
