  A series of 4-aroyl-1,3-dihydro-2H-imidazol-2-ones was synthesized and evaluated for pharmacological activity in the anesthetized dog. Most members of this series produced dose-related increases in cardiac contractile force as well as relatively minor increases in heart rate and decreases in systemic arterial blood pressure that were not blocked by propranolol. In general, 4-methoxy or 4-methylthiobenzoyl substitution afforded compounds of greatest inotropic potency. 1,3-Dihydro-4-(4-methoxybenzoyl)-5-methyl-2H-imidazol-one (6) was shown to produce a dose-related positive inotropic effect and reverse the depressant effect of pentobarbital on cardiac pump function in the dog heart-lung preparation. The cardiotonic activity of this series may have important utility in the treatment of congestive heart failure. 1,3-Dihydro-4-[4-(methylthio)benzoyl]-5-methyl-2H-imidazol-2-one (17) was chosen for human studies and is currently undergoing clinical trials.

  Aryl methyl ketones 1a-e gave with N,N-dimethylacetamide dimethylacetal (DMADMA) ( E)-1aryl-3-(dimethylamino)-but-2-en-1-ones 2a-e. Substitution of the N,N-(dimethylamino) group in the reaction with ammonium acetate afforded the cor responding ( Z)-3-amino-1-aryl-but-2-en-1ones 3a-e. In the reaction of 3a-e with diethyl azodicarboxylate intermediates 4a-e were formed, which were, in most cases without
