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.
本文披露了.alpha.-[(烷基氨基)甲基]-.beta.-芳氧基苯乙醇,具有抗心律失常活性,其化学式如下:##STR1##其中R为氢、卤素、低烷基或低烷氧基;X为苯基、1-萘基或由卤素、低烷基或低烷氧基取代的苯基;R.sub.1为低烷基;以及其药学上可接受的酸盐。此外,本文还披露了一种在3-苯基-2-环氧丙酰胺的3位上添加芳氧基的方法,以产生.alpha.-羟基-.beta.-芳氧基苯丙酰胺,该方法包括在冠醚的存在下将碱金属芳氧化物与所述3-苯基-2-环氧丙酰胺接触。这种.alpha.-羟基-.beta.-芳氧基苯丙酰胺可以还原以产生本发明中的化合物。
