Abstract: The title compound was prepared by treatment of 1-(2-chlorophenyl)-3-methyl-2-pyrazolin-5-one with 2-chlorobenzoyl chloride / Ca(OH)₂ in 1,4-dioxane and subsequent cyclization of the thus obtained 4-aroyl-5-hydroxypyrazole with sodium hydride in dry DMF. Detailed spectroscopic data (¹H NMR, ¹³C NMR, ¹⁵N NMR, IR, MS) are presented.
