Synthesis and biological activity of arylaliphatic <italic>N</italic>-(2-aminoethyl)-<italic>N</italic>-(2-hydroxy-2-phenylethyl)carboxamides.

<italic>N</italic>-(2-Aminoethyl)-<italic>N</italic>-(2-hydroxy-2-phenylethyl)carboxamides were synthesized from styrene oxide by ring opening with <italic>N</italic>,<italic>N</italic>-disubstituted ethylenediamines followed by <italic>N</italic>-acylation. Synthesized compounds have pronounced antiarrhythmic activity and low toxicity. [ABSTRACT FROM AUTHOR]
