4-Arylmethylidene-4,5-dihydro-1,3-diphenylpyrazol-5-ones were synthesized by the convenient three components condensation reaction of ethyl benzoylacetate, phenyl hydrazine and aromatic aldehydes in the presence of acetic acid. This method shortened reaction time and products were obtained in moderate yields. All products were identified by MS, lH NMR, IR techniques and elemental analysis.

Key words: 4-arylmethylidene-4,5-dihydro-1,3-diphenylpyrazol-5-one, three component condensation, one-pot synthesis
