Two pyrazoline analogs 3- (2-methoxy-phenyl) -5-naphthalene-1-yl-1-phenyl-4,5-dihydro-pyrazole (PF CL-2OMe) and 3-(2-methoxy-phenyl)-5-naphthalene-1-yl-4,5-dihydro-1H-pyrazole (PH CL-2OMe) were synthesized by cyclisation reaction between the (E)-1-(2-methoxy-phenyl)-3-naphthalene-1-yl-propenone (CL-2OMe) and two hydrazine derivatives, phenylhydrazine and hydrazine hydrate using a basic catalyst…
