Abstract
The pyrazole-carboxylic acid chloride 2 was obtained from the reaction of 4-Benzoyl-l-(2,4-dinitrophenyl)5-phenyl-l//-pyrazole-3-carboxylic acid 1 and thionyl chloride. l//-PyrazoIe-3 carboxylic acid chlorides 2 can easily be converted into corresponding l//-pyrazole-3-carboxylic acid amide derivatives 4 and l//-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, and C NMR spectroscopic data and elemental anaylsis.
