Preparation of 2-[1-Phenyl-1H-pyrazol-5-yl]benzoic Acids from DilithiatedC(α),N-Phenylhydrazones and Methyl Hydrogen Phthalate

Autor: John D. Knight, Anna C. Dawsey, N. Dwight Camper, Charles F. Beam

Publikováno v: Synthetic Communications. 38:4150-4159

Select C(α),N-phenylhydrazones were dilithiated with excess lithium diisopropylamide to their dianion-type intermediates followed by condensation with methyl hydrogen phthalate. The resulting C-acylated hydrazones were not isolated but acid cyclized
