Chemistry of substituted quinolinones. Part II synthesis of novel 4- pyrazolylquinolinone derivatives

4-Hydrazino-1-methyl-2(1H)quinolinone (2) was treated with chlorophthalazine, nitrous acid, isothiocyanates and isatines, and also utilized as a precursor for some new 4-pyrazolylquinolinones. Reaction of 2 with certain 3-acylquinolinones afforded quinolinylpyrazoloquinolinones and/or quinolinylpyrazolylquinolinones.
