(1R,2S,5R)-2-Benzyloxycarbonylamino-7-oxo-6-aza-bicyclo[3.2.1]octane-6-carboxylic acid tert-butyl ester (500 mg, 1.3 mmol) was dissolved in THF (10 mL) and water (2.2 mL) prior to the addition of NaBH4 (252.4 mg). After 5 h, the reaction was quenched with saturated NaHCO3 solution and extracted with EtOAc (2×). The organic extracts were combined, dried (MgSO4), filtered, and concentrated in vacuo to afford tert-butyl (1R,3R,4S)-4-benzyloxycarbonylamino-3-(hydroxymethyl)cyclohexylcarbamate (505 mg). MS (ES+)=375.4 (M+H)+.
