実験手順

6.7 g (22 mmol) of tert.-butyl N-(trans-1-benzyl-4-methoxypyrrolidin-3-yl)carbamate are hydrogenated in 150 ml of methanol on 2 g of palladium-on-active charcoal (10% of Pd) under 100 bar at 100° C. The catalyst is filtered off with suction, the filtrate is concentrated and the residue is distilled.
