SYNTHESIS AND SPECTRAL CHARACTERIZATION OF SOME NEW PYRAZOLINE DERIVATIVES
Journal Title: WORLD JOURNAL PHARMACY AND PHARMACEUTICAL SCIENCE - Year 2018, Vol 7, Issue 1
Abstract
The title compounds were synthesized by condensation azachalcones with ethylacetoacetate to get intermediate 3-(pyridyl)-5-aryl-6- ethylcarboxylate-2-cyclohexenone which were subsequently treated with hydrazine hydrate to afford the title compounds 4-(pyridyl)-6- aryl-7one-5,6-dihydro-1Hindazol or pyrazoline derivatives.[1-10] The sructures of the final products were supported by spectral data (UV, IR, 1HNMR) in addition to their physical properties.
