    • PROBLEM TO BE SOLVED: To provide a process of production in which epimerization and oxidation of tigecycline are controlled in bulk production.
      SOLUTION: This specification discloses a process of production for a formulation of tigecycline suitable for intravenous infusion. Specifically, an important feature is to control the temperature and oxygen level during the steps of the process. Tigecycline is protected during the process by injection of an inactive gas medium containing a non-reactive gas (e.g., nitrogen) and temperature control. The embodiment of the invention provides a production of tigecycline whose amount of decomposition products is less than 0.9% in total by controlling the temperature of an aqueous bulk solution thereof and the level of dissolved oxygen.
