A series of 6-(N-linked, five membered heteroaryl)-2(1H)-quinolinone derivatives was synthesized and evaluated for cardiotonic activity. Most compounds were prepared by sulfuric acid catalyzed cyclization of an N-(4-heteroarylphenyl)-3-ethoxypropenamide o

A series of novel heterocyclic-substituted 1,2,3,5-tetrahydroimidazo(2,1-b)quinazolin-2-(1H)-one compounds have been prepared, including their pharmaceutically acceptable salts, wherein the heterocyclic ring moiety is an optionally substituted 5- or 6-membered aromatic heterocyclic group attached to the 6-, 7-, 8- or 9-positions of the aforesaid tetrahydroquinaxolinone ring. These particular compounds are useful in therapy as highly potent inotropic and therefore, are of value in the treatment of various cardiac conditions. Preferred member compounds include 7-(2,4-dimethylimidaxol-1-yl)-9-methyl-1,2,4,5,-tetrahydroimidazo (2,1-b)quinazolin-2-(1H)-one, 3,9-dimethyl-7-(2,4-dimethylimidazol-1-yl) -1,2,3,5-tetrahydroimidazo(2,1-b)quinazolin-2-(1H)-one and 9-methyl-7 -(1,2,4-triazol-4-yl)-1,2,3,5-tetrahydroimidazo(2,1-b)quinazolin-2-(1H)-one, respectively. Methods for preparing these compounds from known starting materials are provided.
