Abstract
Disclosed herein are .alpha.-[(alkylamino)-methyl]-.beta.-aryloxy-benzeneethanols exhibiting antiarrhythmic activity and having the following formula: ##STR1## wherein R is hydrogen, halogen, lower alkyl, or lower alkoxy; X is phenyl, 1-naphthyl, or a phenyl group substituted by a halogen, a lower alkyl group, or a lower alkoxy group; R.sub.1 is lower alkyl; and pharmacologically acceptable acid addition salts thereof. Also disclosed is a process for the addition of an aryloxy group at the 3-position of a 3-phenyl-2-oxiranecarboxamide to produce an .alpha.-hydroxy-.beta.-aryloxy-benzenepropanamide, said process comprising contacting an alkali metal aryloxide with said 3-phenyl-2-oxiranecarboxamide in the presence of a crown ether. Such .alpha.-hydroxy-.beta.-aryloxy-benzenepropanamides may then be reduced to produce the compounds of the invention.
