Process for the purification of a 3-cephem-4-carboxylic acid derivative |
| abstract |
The invention relates to a new process for the depletion of 7-amino-3-[(E)-1-propen-1-yl]-3-cephem-4-carboxylic acid in mixtures of 7-amino-3-[(Z)-1-propen-1-yl]-3-cephem-4-carboxylic acid and 7-amino-3-[(E)-1-propen-1-yl]-3-cephem-4-carboxylic acid, by means of the crystalline hydrochloride or a metal or amine salt of 7-amino-3-[(Z/E)-1-propen-1-yl]-3-cephem-4-carboxylic acid or by adsorption chromatography. |
