A series of 3'-(O-acyl) derivatives of etilefrine (alpha-[(ethylamino)methyl]-3'-hydroxybenzyl alcohol) was synthesized. Correlations between structure and solubility, pKa value, lipophilicity, and esterase-catalyzed hydrolysis were demonstrated. Of special interest is the 3'-(O-pivaloyl) derivative, which shows, in addition to favorable solubility and improved lipophilicity, marked stability against
