摘要：
Vilsmeier-Haack reaction of (E)-1[1-(3,5-difluorophenyl)ethylidene]-2-phenylhydrazine (1) using dimethyl formamide in excess of phosphorus oxychloride by conventional method, resulted in the synthesis of the title compound 3-(3,5-difluorophenyl)-1-phenyl-1H-pyrazole-4- carbaldehyde (2) in good yield and high purity. Structure characterization of the title compound was done by IR, H-1-NMR, C-13-NMR and HRMS spectral analysis.
