Abstract
Two sulfur-containing alkamine esters, p-diethylaminosulfonylbenzoyldiethylaminoethanol and p-ethylsulfonylbenzoyldiethylaminoethanol, can be obtained as their hydrochlorides by the application of the corresponding acid chloride to diethylaminoethanol in anhydrous benzene. These esters form crystalline salts with penicillin.
