Abstract
The present invention relates to a process for the preparation of 1-(m- and p- hydroxyphenyl)-2-aminoethanol which consists of converting an m- or p- hydroxyacetophenone to an isonitrosoketone followed by hydrogenation of the isonitrosoketone. These compounds are sympathomimetics which produce vasoconstricting and cardiotonic effects.
