Abstract
Compound of 4-(ethoxycarbonyl)-1,5-diphenyl-1H-pyrazole-3-carboxylic acid was obtained from the reaction of ethyl 4,5-dioxo-2-phenyl-4,5-dihydrofuran-3-carboxylate and 1-benzylidene-2-phenylhydrazine. A number of substitute pyrazole dicarboxylic acid derivatives (, , , , , , , , , , ) were synthesized from 1,5-diphenyl-1H-pyrazole-3,4-dicarboxylic acid which was prepared from basic hydrolysis of . Structures of synthesized compounds were characterized by 1H NMR, 13C NMR, Mass, FTIR, and elemental analysis. J. Heterocyclic Chem., (2010).
