Abstract
Process for the preparation of amino-alkyl esters of methylenampicillin, characterized in that an alkaline salt of methylenampicillin is reacted with an alkyl ester of chloroformic acid to obtain, as an intermediate and unstable product, a mixed anhydride of methylenampicillin, which it is reacted with an amino alcohol, in ketone medium.
