Abstract: The reaction of 3-methyl-1-phenyl-2-pyrazolin-5-one and 2-bromo-3-furoyl chloride in the presence of Ca(OH)₂ in 1,4-dioxane gave the title compound. The latter was also obtained in much higher yield upon reaction of the starting materials in the system dichloromethane / triethylamine. Detailed spectroscopic data (¹H NMR, ¹³C NMR, ¹⁵N NMR, IR, MS) are presented.

Keywords: pyrazolones; aroylation; NMR spectroscopy
