An efficient synthesis of 3-(3-methyl-1-aryl-1H-pyrazol-5-yl)-2H-2-chromen- 2-one derivatives by the reaction of salicylaldehydes, 4-hydroxy-6-methyl-2H- pyran-2-one, and arylhydrazine in acetonitrile under reflux condition and in the presence of piperidine is reported. This three-component reaction has some advantages such as ease of handling, good yields, and easy purification. All structures were confirmed by infrared, mass, 1H NMR, and 13C NMR spectroscopy.
