Reaction of 4-amino-1-methyl-1H-1,2,4-triazolium iodide with dimethyl acetylenedicarboxylate or methyl propiolate in the presence of alkali followed by heating with water gave methyl 1H-pyrazole-4-carboxylates in low yields, and reaction of 4-acylimino-1-methyl-1H-1,2,4-triazolium betaines with methyl propiolate afforded 5-substituted 1-methyl-1H-1,2,4-triazoles.
