title: Synthesis and antiarrhythmic activity of 2-dialkylaminoalkyl-9-phenyl-1H-indeno[2,1-c]pyridine derivatives.
abstract: Some dihydro- and hexahydro-2-dialkylaminoalkyl-9-phenyl-1H-indeno[2,1-c]pyridines were prepared and found to possess significant antiarrhythmic activity. Hydrogenation of the dihydro compounds 4 produced the allcis-hexahydro isomers 5 which were consistently active in three assays against induced ventricular arrhythmias. On the other hand, the H9H9a-trans isomers, which were obtained by basic equilibration of the cis isomers, were less effective.
