Abstract
Abstract By using of the double-labelled C * N * - CH 2 - COOEt compound it has been proved that transformation of 6-nitro-1,2,4-triazolo[1,5-a]pyrimidine into 2-triazolylamino-3-carbethoxy-5-nitropyridine proceeds with incorporation of the C-C-N fragment of ethyl cyanoacetate into the pyridine ring.
