Abstract: A new method was carried out for the synthesis of 2,4-thiazolidinedione 3 by heating thiourea and chloroacetyl chloride in water under ultrasonic irradiation. Moreover, a rapid and green method has been developed for the synthesis of a series of diaryl substituted pyrazolyl-2,4-thiazolidinediones 8a-g through the reaction of appropriate pyrazolecarboxaldehydes 7a-g with 2,4-thiazolidinedione 3 using β-alanine as a catalyst. All compounds were characterized by their reported melting points, FT-IR, 1H and 13C NMR spectroscopy in addition to elemental analysis. This new synthetic method has advantages of being gives a product with high purity, good yield, and short reaction times when compared to the previously reported methods.
