Versuchsvorschrift

To a solution of 1,1-dimethylethyl 4-[(3-bromophenyl)methylidene]-1-piperidinecarboxylate (201 mg, 0.571 mmol) in THF (1 mL) was applied onto H-Cube using 10% Pd/C at a flow rate of 1 mL/min and 1 atm H2. The mixture was concentrated to afford 0.1909 g (94%) of the title compound. LC-MS m/z 354 (M+H)+.
