Versuchsvorschrift

4-Piperidinecarboxamide (10.2 g, 78.0 mmol) in DMSO (10 mL) was treated with benzyl bromide (20.0 mL, 168 mmol). The mixture was diluted with EtOAc and washed with 1N aq. HCl, 5N aq. NaOH, dried over MgSO4, and concentrated to give 5.90 g (35%) of N-benzyl-4-piperidinecarboxamide. [1H]-NMR(CDCl3) consistent with structure.
