Dialkylaminoalkyl ethers of 2,2'- and 3,3'-dihydroxybenzil are prepared by reacting the dithallium salt of 2,2'- or 3,3'-dihydroxybenzil with a dialkylaminoalkylchlorde. The products have antiarrhythmic activity.

A series of 3-(aminoalkyl)benzopyrano[3,4-c]pyridin-5-ones was prepared and tested as potential orally active anticholinergic bronchodilators. Inhibition of methacholine-induced collapse in guinea pigs and inhibition of pilocarpine-induced bronchoconstriction in dogs served as in vivo models. Simultaneous measurement of salivary inhibition in the dog model allowed determination of a pulmonary selectivity
Novel 2-aryl-2-[.omega.-(diisopropylamino)alkyl]-.omega.-(azabicycloalkyl)alkana mides are described herein. The present compounds are useful as anti-arrhythmic agents. The compounds are prepared by reacting an appropriate disubstituted acetonitrile with an appropriate .omega.-(azabicycloalkyl)alkyl halide and subsequent hydrolysis of the resulting nitrile with concentrated sulfuric acid.
