SYNTHESIS OF SOME NEW DERIVATIVES OF 1,3,4,5- TETRASUBSTITUTED-1H-1,2,4-TRIAZOLES BY REACTION OF NITRILIMINES WITH ALDEHYDE METHOXYCARBONYIHYDRAZONES

Abstract

Nitrilimines (2a-e) react with aldehyde methoxycarbonylhydrazones (3-5) to afford 3-acetyl-5-alkyl-1-aryl-4- (methoxycarbonylamino)-4,5-dihydro-1H-1,2,4-triazoles (6-8a-e). The structure of these compounds was elucidated by IR, MS and NMR spectral data.
