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.
本公开涉及表现出抗心律失常活性的α-[(烷基氨基)-甲基]-β-芳氧基苯乙醇,其具有以下结构式:其中R为氢、卤素、低烷基或低烷氧基;X为苯基、1-萘基或被卤素、低烷基或低烷氧基取代的苯基;R.sub.1为低烷基;以及其药理学上可接受的酸盐。还公开了一种在3-苯基-2-氧环丙酰胺的3位加入芳氧基团的方法,以制备α-羟基-β-芳氧基苯丙酰胺,该方法包括在冠醚存在下将碱金属芳氧化合物与所述3-苯基-2-氧环丙酰胺接触。这种α-羟基-β-芳氧基苯丙酰胺随后可被还原以产生本发明的化合物。
