Process development work to provide an efficient, robust, and cost-effective manufacturing route to avibactam, a β-lactamase inhibitor is presented herewith. Aspects of this optimization work include the counterintuitive introduction of a protecting group to effect a difficult urea formation and the use of controlled feed hydrogenation conditions to facilitate an elegant one pot debenzylation and sulfation reaction. Overall, the commercial process delivers avibactam in much improved yield with significant reduction in the environmental footprint.

Paragraph 0175; 0176, (2018/03/07)
The present invention relates to a compound of Formula (I)-(IV) useful as β-lactamase inhibitor, a pharmaceutically acceptable salt, ester, solvate or stereoisomer thereof, wherein R1, R2, M and ring A have definitions as those in the specification. The present invention further relates to methods for preparing these compounds, pharmaceutical compositions comprising these compounds, and uses of these compounds. For example, the compounds of the present invention can be used as β-lactamase inhibitors, for treatment and/or prophylaxis of diseases caused by bacterial infections, solving drug-resistance problems caused by β-lactamases, especially bacterial drug-resistant diseases caused by type B metallo-β-lactamases.
