    1-(2-hydroxy-3,4-benzophenyl-5-methoxy)-3aryl-prop-2-ene-1-one &  semicarbazide / thiosemicarbazide / phenylhydrazine /isonicotinic acid hydrazide were added to DMF and the mixture was refluxed for about 2 hours . The reaction mixture was cooled and diluted with water. The semisolid so obtained was triturated  with ethanol to get a solid which was  recrystallised from ethanol–acetic acid mixture to obtain titled pyrazolines&nbsp
