Amidines obtained from benzamides and DMF‐ or DMA‐dimethylacetal were cyclized with phenylhydrazines to 3H‐ or 3‐methyltriazoles. 3‐Ethyltriazoles were synthesized from diacylamides. Triazole‐3‐carboxylic acides were prepared starting from anilines. The compounds were assayed in the rat adjuvant induced arthritis model. Some compounds show significant anti‐inflammatory activity.
