| titleOfInvention | Intermediates and crystals for the preparation of cephem compounds |
| abstract | The present invention discloses intermediates and crystals for preparing cephem compounds, in particular to intermediates for preparing cefdrolizan, crystals of the intermediates and a method for preparing cefdrolzan. The use of intermediates in solid form (amorphous and crystalline) to prepare cefdrolizan sulfate significantly reduces the content of impurities, and the obtained product has high yield, good purity and simple post-processing, and is more suitable for industrial production. |
