Procedure

If methanol or isopropanol is used in place of ethanol in the reaction with the carboxylic acid chloride of 2-(p-tolyl)-4-carboxy-2H-1,2,3-triazole, the corresponding methyl ester or, respectively, isopropyl ester is obtained. These esters can be converted, in the manner described above, into 2-(p-formyl-phenyl)-4-carbomethoxy-2H-1,2,3-triazole (melting point: 125° to 127° C.) and, respectively, 2-(p-formyl-phenyl)-4-carboisopropoxy-2H-1,2,3-triazole (melting point: 100° to 102° C.).
