3-Methyl-1-phenyl-1H-pyrazol-5-yl 2-Bromo-3-furan-carboxylate

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 spect...

Summary: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.
