2-lmino-4-carbomethoxy-s-triazino[2,1-b) benzothiazoles, benzoxazoles, and thiazoles (VI), and XIII were synthesized in combination with their 4-carboxylic acid derivatives (VII) & (XIV), via the cyclization their 4-carboxylic acid derivatives (VII) & (XIV), via the cyclization reaction of their corresponding 2-guanidine salts with diethyl oxalate. Reaction of 4-carbomethoxy-s-triazines with hydrazine hydrate gave the corresponding hydrazides (VIII), from which hydrazones (IX) were prepared. Cyclization of 2-guanidine heterocyclic salts with ethyl chloroacetate afforded 2-imino-4-chloromethyl-s-triazines (V & XII) in fair yields. Some of the synthesized compounds were studied through their ir, nmr spectra.
