Reaction Steps

BCl3 (1M, 3.34 mL, 3.33 mmol) was added to a solution of (2S,5R)-6-(benzyloxy)-2-(1,2,4-oxadiazol-3-yl)-1,6-diaza-bicyclo[3.2.1]octan-7-one (200 mg, 0.67 mmol) in dry DCM (45 mL) at −78° C. The mixture was stirred at 0° C. for 2 hrs., then it was cooled to −78° C. and quenched with MeOH (8 mL). The solvent was removed by vacuum to give (2S,5R)-6-hydroxy-2-(1,2,4-oxadiazol-3-yl)-1,6-diaza-bicyclo[3.2.1]octan-7-one (180 mg) as a white solid, which was used directly in the next step. ESI-MS (EI+, m/z): 209 [M−H]+.
