Novel acyloxy-phenylethanolamines, characterized in that the acyloxy group or groups are pivaloyloxy or phenylacetyloxy and having a more prolonged sympaticomimetic action than acyloxy-phenylethanolamines known previously, are described together with a method for their manufacture by reduction of the corresponding acyloxy-phenylketo-N-benzyl amines using hydrogen in an aqueous medium over a noble metal catalyst.
