An unambiguous synthesis of 1-(2-diethylaminoethyl)-3,4-pentamethylenepyrazole (III) by acid cyclization of 2-(2-cycloheptanonyl)-1,3-dioxolane 2-diethylaminoethylhydrazone, and of N2-methyl and N2-(2-diethylaminoethyl)bornylenepyrazole (VIII) and (IX), by heating the hydrazones from 3-hydroxymethylene-2-bornanone and methylhydrazine or 2-diethylaminoethylhydrazine respectively, is described. (III) showed antiinflammatory activity and (VIII) an anticonvulsant action.
