    摘要: The present invention provides:

    an industrially-excellent and novel process for producing a basic antibiotic·inorganic acid salt, for example, an excellent production process for producing a hydrochloride thereof industrially, that is, a production process which comprises subjecting a basic antibiotic·oxalate (II) to salt-exchange with an alkali earth metal salt (III) of an inorganic acid:
    (wherein the ring A means the basic antibiotic; R 10 means a protected functional group used in organic synthesis; Ak-E means the alkali earth metal; and B means the inorganic acid, respectively);
    a novel oxalate useful as a production intermediate for producing an antibiotic·hydrochloride industrially, that is, an oxalate (II-I) of a carbapenem compound represented by the following formula:
    (wherein the ring A represents a 3- to 7-membered ring having at least one nitrogen atom, and the ring A may be substituted with other than R 6 ; R 1 represents hydrogen or methyl group; R 2 and R 5 are the same as or different form each other and each represents hydrogen or a hydroxyl-protecting group; R 3 represents a carboxyl-protecting group; R 4 represents hydrogen, a lower alkyl group or an amino-protecting group; R 6 represents (1) hydrogen, (2) an optionally protected hydroxyl group, carbamoyl, formimidoyl, acetoimidoyl or a lower alkyl group which may be substituted with a substituent represented by the formula:
    (wherein R 7 and R 8 are the same as or different from each other and each represents hydrogen, a lower alkyl group or an amino-protecting group) or (3) an amino-protecting group or an imino-protecting group; and m is 0 or 1); and
    a process for producing its.
