Procedure

9-Benzyl-7-oxo-9-aza-bicyclo[3.3.1]nonane-3-carboxylic acid ethyl ester (11.1 g, 36.8 mmol) was dissolved in methanol (30 mL) and added to a suspension of palladium hydroxide (1 g) in methanol (10 mL) in a Parr bottle. The Parr bottle was filled with hydrogen (30 psi) and evacuated three times. The Parr bottle was refilled with hydrogen (30 psi) and shook for 12 h. The suspension was filtered through Celite and concentrated under vacuum to give 7.81 g (quantitative yield) of 7-oxo-9-aza-bicyclo[3.3.1]nonane-3-carboxylic acid ethyl ester as a yellow oil. Retention time (min)=0.369, method [1], MS (ESI) 212.1 (M+H).
