Procedure

A solution of 2-aza-2-benzyl-4-oximino-3-oxobicyclo[3.2.1]octane in 10 mL/mmole of ethanol and 5.8 mL/mmole of 3N HCl containing 0.5 g/mmole of 10% Pd/C was saturated with hydrogen gas to 45 psi. The mixture was shaken for 3 hours and then filtered through a layer of Celite. The filtrate was dried over sodium sulfate and concentrated under reduced pressure to afford the title compound as a solid (86% yield). This procedure is further described in E. Reimann, Arch. Pharm. 310, 102-109 (1977).
