Abstract
Tazobactam is a β-lactamase inhibitor. In this work, a combination of continuous flow and batch experiments for the synthesis of tazobactam has been developed. The first three steps and the preparation of the peroxyacetic acid are continuously carried out in the microreactors, which improves the procedure safety and efficiency. There is also a final step of the deprotection reaction in the microreactor, which can increase the yield and reduce the formation of impurities. Under optimized process conditions, the total yield of the target product reached 37.09% (30.93% in batch). The continuous flow method not only greatly reduces the reaction time but also significantly improves procedure safety and increases the yield.
