Crystalline cefdiniric acid addition salt and method for producing cefdinir using the same |
| abstract |
Crystalline cefdiniric acid addition salt, process for producing the same, and process for producing cefdiniric acid using the same are disclosed. Cefdinir intermediate is reacted with mixed acid of formic acid-sulfuric acid or formic acid-methanesulfonic acid. High purity cefdinir can be produced in high yield by the process of the present invention comprising: obtaining a crystalline cefdinir salt; and reacting the resulting crystalline salt with a base in a solvent.
