Method of preparation od clavulanic acid, its using and its salts |
| abstract |
A process for the preparation and/or purification of clavulanic acid or a pharmaceutically acceptable salt thereof comprises i) contacting impure clavulanic acid or an alkali metal salt thereof in an organic solvent, with tertiary octylamine; ii) isolating the tertiary-octylamine salt of clavulanic acid formed; iii) converting the thus formed salt into clavulanic acid or a pharmaceutically acceptable salt or ester thereof. |
