Abstract:N-(2-Aminoethyl)-1-(4-chlorophenyl)-5-methyl-1,2,3-triazole-4-carboxamide was synthesized through five steps using 4-chlorobenzenamine as the starting material. The reaction conditions between triazole ester and ethylene diamine were explored and determined as follows: reaction temperature around 78℃, reaction time 8 h, n(triazole ester): n(ethylenediamine)=1:25. The yield of the topic compound was up to 88% and the product was characterized by 1H NMR and MS.
Key words:heterocyclic compounds; carboxamide; triazole
