Process for the Preparation of Crystalline Form C of Avibactam Sodium |
| abstract |
The invention relates to a process for the preparation of avibactam sodium in polymorphic form C comprising the steps (i) providing a mixture comprising avibactam or a salt thereof and a solvent, wherein the mixture has a water content of less than 2% by weight based on the weight of the mixture; (ii) increasing the temperature of the mixture provided in (i) to at least 55° C. and providing a positive pressure; adding a sodium source to the mixture in step (i) and/or (ii) if the form of avibactam provided in (i) is not avibactam sodium; thereby obtaining avibactam sodium in polymorphic form C. |
