Abstract:We have described some novel Sulphonamide bearing pyrazoline derivatives synthesized by conventional method as well as microwave assisted method of synthesis. The reaction of 4-(3-methyl-5-oxo-4,5-dihydro-1-H-pyrazol-1-yl)benzenesulphonamide with substituted benzaldehyde in the presence of Methanol as solvent and piperidine as catalyst, generated a series of substituted pyrazolone derivatives 4a-m. The structures of all synthesized compounds are well characterized by Mass spectroscopy, FT-IR, 1 H NMR and eleme… Show more
