A general procedure for synthesis of 5-chloro-1H-1,2,3-triazole-4-carboxaldehydes 4 and the rearrangement reaction of 4-(N-substituted)iminomethylene-1H-1,2,3-triazol-5-ols 6 into N-substituted-1H-1,2,3-triazole-4-carboxamides 7 are described.

An Expeditious Synthesis of 4-Alkoxycarbonyl-5-hydroxy-1,2,3-triazoles: the Crystal and Molecular Structure of the 2-Thienylammonium Salt of 5-hydroxy-4-methoxycarbonyl-1-(2-thienyl)-1,2,3-triazole

Dimethyl diazomalonate undergoes reaction with primary alkyl amines to generate the corresponding primary ammonium salts of 1-alkyl-5-hydroxy-4-methoxycarbonyl-1,2,3-triazoles; the structure of the product from the reaction of the diazoester with 2-thienylamine has been confirmed by X-ray methods.
