were cyclized with nucleophiles like phenyl hydrazine / semicarbazide / thiosemi carbazide in DMF solvent and refluxed for 2 hours. The cooled reaction mixture was diluted with water the semisolid so obtained was triturated with ethanol to get a solid which was recrystallised from ethanol-acetic acid mixture to get pyrazoline derivatives. The synthesized compounds were characterized by elemental analysis, 1H NMR, IR Spectroscopy.
