Hybrid systems containing pyrazole moiety show a wide spectrum of biological activities. To access novel hybrids with pyrazole ring, in this work we synthesized twenty pyrazole-carboxylic acids and twenty pyrazole-carboxamides, using simple synthetic methods, to be used as building blocks in the development of new structures.

A series of new 5-(1-aryl-1H-pyrazole-4-yl)-1H-tetrazoles 4a-l were synthesized via [3 + 2] cycloaddition reaction from 1-aryl-1H-pyrazole-4- carbonitriles 3a-l, sodium azide and ammonium chloride, using dimethylformamide (DMF) as solvent, in good yields: 64-85%. The structures of these newly synthesized compounds were determined from the IR, 1H- and 13C-NMR spectroscopic data and elemental analyses.
