Azoic Compounds Obtained from 1H-5-Amino-4-ethoxycarbonyl-3-methyl-pyrazole and Phenols or Phenolic Derivatives

Abstract

The coupling of 1H-4-ethoxycarbonyl-3-methyl-pyrazol-5-yl-diazonium chloride with phenols and phenolic derivatives affords the corresponding 1H-4-ethoxycarbonyl-3-methyl-5-arylazo-pyrazoles, which were characterized by TLC, IR, VIS and NMR spectroscopy.
