Procedure

To a solution of N,N,N-tributylbutan-1-aminium ({[(2S,5R)-2-({[(3R)-1-(tert-butoxycarbonyl)piperidin-3-yl]oxy}carbamoyl)-7-oxo-1,6-diazabicyclo[3.2.1]oct-6-yl]oxy}sulfonyl)oxidanide 15 (0.30 g, 0.42 mmol) in DCM (17 mL) was added trifluoroacetic acid (0.84 mL, 10.9 mmol) dropwise at 0° C. The reaction mixture was stirred for 1 h, then evaporated. Ether was added to the residue and the resulting white precipitate was collected by centrifugation. The solid was triturated with acetonitrile (2×) and the white solid was collected by centrifugation. The white solid was purified by HPLC and freeze-dried to give (2S,5R)-7-oxo-N-[(3R)-piperidin-3-yloxy]-6-(sulfooxy)-1,6-diazabicyclo[3.2.1]octane-2-carboxamide Compound 3 (Table 1) (0.045 g, 29.41%) as a white solid.
