YieldReaction ConditionsOperation in experiment
In toluene;Reflux; General procedure: The appropriate 1-substituted-3-methyl-5-aminopyrazole 46 (1.0 mmol) and the aldehyde 47 (1.0 mmol) were heated under reflux in toluene (50 mL) for 7-9 hours; during this period produced water was removed with the aid of a Dean-Stark apparatus. The reaction mixture was cooled, 2-mercaptopropanoic acid (1.0 mmol) was added and the mixture heated again at reflux for 12 hours. The solvent was removed in vacuo and the residue submitted to medium pressure liquid chromatography. Elution by light petroleum-ethyl acetate mixtures afforded the desired compounds.
