Abstract

Abstract The reaction of ethyl 4-formyl-1-phenyl-1 H-pyrazole-3-carboxylate with the malonic acid led to the formation (2 E)-3-(3-ethoxycarbonyl-1-phenyl-1 H-pyrazol-4-yl) propenic acid. In reactions of this acid chloride with 4-amino-5-aryl (hetaryl)-4 H-1, 2, 4-triazole-3-thiols were obtained ethyl 4-[(E)-2-{3-aryl (hetaryl)[1, 2, 4] triazolo [3, 4-b][1, 3, 4] thiadiazol-6-yl} ethenyl]-1-phenyl-1 H-pyrazoe-3-carboxylates, with 5-aryltetrazoles, ethyl 4-[(E)-2-(5-aryl- ...
