Özet

The pyrazole-carboxylic acid chloride 2 was obtained from the reaction of 4-Benzoyl-1-(2,4-dinitrophenyl)-5-phenyl-1H-pyrazole-3-carboxylic acid I and thionyl chloride. 1H-Pyrazole-3 carboxylic acid chlorides 2 can easily be converted into corresponding 1H-pyrazole-3-carboxylic acid amide derivatives 4 and 1H-pyrazole-3-carboxamide derivatives 6 from the reaction with various aliphatic and aromatic amines. The structures of these new synthesized compounds were determined from the IR,(1)H and (13)C NMR spectroscopic data and elemental anaylsis.
