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
