    摘要: The invention provides compounds of the general formula
    wherein X is -Cl, Br or -OCH 2 CH 3 , and the preparation thereof. One such compound, 1-bromoethyl ethyl carbonate, is useful as an esterification agent, e.g. for penicillins, and the other such compounds are intermediates in its preparation. The manufacture of formulations containing 1 '-ethoxycarbonyloxy ethyl esters of penicillins is included in the invention.
    There are also provided novel compounds of the formula
    in which Ph is phenyl and R is CH 3 - or C 2 H 6 -.
