Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 7.2 g (33 mmol) of 8-benzyl-2-oxa-5,8-diazabicyclo-[4.3.0]nonane are hydrogenated in 400 ml of methanol with 2.5 g of palladium-on-active charcoal (10% of Pd) under 50 bar at 100° C. The catalyst is filtered off with suction, the filtrate is concentrated and the residue is distilled. The catalyst is filtered off with suction the filtrate is concentrated the residue is distilled
