Title: Preparation of alkali-metal alpha-carboxypenicillin salts  and new forms thereof
IPC: C07D499/72
Filed: 1971-10-13
Abstract: 1311454 Purifying α-carboxypenicillin salts BEECHAM Inc 13 Oct 1971 [22 Oct 1970] 47620/71 Heading C2A α - Carboxypenicillin di(alkali - metal) salts having the general formula wherein R is phenyl, substituted phenyl, thienyl or furyl and M is alkali-metal, are produced by treating the free α-carboxypenicillanic acid (i.e. as above but wherein M is hydrogen) with a basic alkali-metal salt in a water immiscible organic solvent to precipitate an alkali-metal salt of the said acid; and purifying the salt by slurrying it in an organic solvent at a temperature of from 40‹ C. to the boiling point of the solvent and then separating and drying the purified di(alkali metal) salt. The invention includes novel disodium α- carboxybenzylpenicillinate and disodium α- carboxy-3-thenylpenicillinate, which salts are characterized by being in crystalline form and having a water content not greater than 1À5% by weight and 2À5% by weight, respectively. The α-carboxypenicillins treated by the process may be conventionally prepared, e.g. by hydrogenolysis or hydrolysis of corresponding esters such as mono- or di-esters with benzyl or ethyl alcohol or phenols; or by enzymatic cleavage of such esters. Conventionally prepared alkali-metal salts of α-carboxypenicillins may also be used, being first converted to the free acid by acidifying in aqueous solution and extracting the resulting free acid into a waterimmiscible solvent. The basic alkali-metal salt may be a sodium alkoxide (e.g. methoxide, ethoxide or butoxide), a sodium phenoxide (e.g. phenoxide or cresylate) or a sodium carboxylate (e.g. ethylhexoate, ethylbutyrate or lactate). The water-immiscible solvent may be a butanol, amyl or isoamyl alcohol, methyl isobutyl ketone, or methyl, ethyl, propyl or butyl acetate. The preferred slurrying solvent is a C 1  to C 5  aliphatic alcohol. After the slurrying treatment, the salt is separated from the solvent and dried below 80‹ C. The penicillin salts thus produced have well-defined crystalline form, a lower water content, greater stability and a lower content of other alkali-metal salts than conventional alkali metal α-carboxy penicillinates.

An element from the temporary storage amends the corresponding element written from the main storage under control of marker tracks MT1, MT2 into a delay track DR on the first revolution of the drum, and a second revolution writes the amended element back into the main storage. At the beginning of the first drum revolution the regenerative loops of both the temporary storage tracks TT1, TT2 and second marker tracks NT1, NT2 are made one element shorter so that the information moves round by one step and then the delays D1, D2 are reinserted. The counting and reading heads W, R are located diametrically opposite each other on each track.
