Substituted benzyl azids were synthesized through the reaction of substituted benzyl chloride and sodium azid, which subsequently underwent cyclization with ethyl propiolate and amidation to give thirteen 1-substituted benzyl-N-substituted-1, 2, 3-triazole-4-formamide derivatives (3a-3m) . The structure of the synthesized compounds was confirmed by IR, 1H-NMR, MS and elemental analysis. Their ant icon vulsant activity against maximal electrolshock (MES) induced seizure was tested and the result showed that all these compounds possess anticonvulsant activity in different degrees. Among those, the compounds containing chloro atoms on the phenyl ring were less potent in anticonvulsant activity, while introducing one or two fluorin atoms on benzyl system increased its activity. Furthermore, their activity decreased when there was substituent on the nitrogen atom of carboxamide, and the larger the substituent, the lower the activity.
