The title compound, 4-benzoyl-5-phenyl-1-p-methoxyphenyl-1H-pyrazole-3- carboxylic acid (C24H18N2O4), was prepared from the reaction of 4-methoxyphenylhydrazine with 4-benzoyl-5-phenyl- 2,3-dihydro-2,3-furandion

(Chemical Equation Presented) The 1H-pyrazole-3-carboxylic acids 2 were converted via reactions of their acid chlorides 3 with some semi- and thiosemicarbazide derivatives into the corresponding new phenylsemi- and thiosemicarbazides 4a-e, 6, 5-(pyrazol-3-yl)-4H-1,2,4-triazol-3-thiones 5a,b, and 2-(pyrazol-3-yl)-1,3,4-thiadiazol 7 derivatives, in good yields (45-97%, respectively). The reactions of 4a,c,e with Lawesson reagent lead to the products 6 and 7 formation. The structures of these newly synthesized compounds were determined. from the IR, 1H- and 13C-NMR spectroscopic data and elemental analyses.
