Versuchsvorschrift

To a stirring solution of BOC-isonipecotic acid (400 mg) in N,N-dimethylformamide (4 mL) was added 1,1′-carbonyldiimidazole (560 mg). The reaction mixture was stirred overnight and then methylamine hydrochloride (280 mg) and triethylamine (0.48 mL) were added. After 5 hours the reaction mixture was diluted with ethyl acetate, washed with water, dried (MgSO4) and the solvent removed in vacuo. Treatment with HCl yielded piperidine-4-carboxylic acid methylamide, which was isolated as the hydrochloride salt.
