thyl-2(1H)-quinolinones was synthesized and evaluated for cardiac stimulant activity in dogs. The majority of compounds were prepared from an appropriate 6-imidazol-1-yl-2(1H)-quinolinone precursor or by sulfuric acid catalyzed cyclization of an N-(4-heteroarylphenyl)-3-ethoxypropenamide. Introduction of a range of 5-substituents into 6-(2,4-dimethylimidazol-1-yl)-8-methyl-2(1H)-quinolinone (1) reduced
