With sodium hydroxide; In ethanol; water; for 4h; | General procedure: A suspension of aromatic aldehyde 1 (40 mmol) and aromaticketone 2 (40 mmol) in mixture of 10 ml saturatedNaOH solution in water and 10 ml ethanol was stirred for 4 hat 20 C to obtain pure chalcone 3 (Ozdemir et al. 2007;Chimenti et al. 2010). Further, mixture of chalcone 3 (10mmol) and thiosemicarbazide (20 mmol) was refluxed understirring with KOH (20 mmol) in 70mL EtOH for approximately6 h to get N-thiocarbamoyl pyrazole derivative 4(Scheme 1). This N-thiocarbamoyl pyrazole derivative 4 (10mmol) was added in appropriate quantity of EtOAc and wasrefluxed with ethyl bromoacetate (30 mmol) for 1.5 h (EISabbaghet al. 2009; Seebacher et al. 2003). After completionof reaction, the reaction mixture was mixed with CHCl3and allowed to evaporate to obtain pyrazol-1-yl-1,3-thaizol-4(5H)-one derivative (5a-5m, Fig. 2). The refined compoundwas obtained by subsequent purification withrecrystallization by using ethanol-acetone (1:1). |
