Versuchsvorschrift

To a solution of (R)-1-(tert-butoxycarbonyl)piperidine-3-carboxylic acid (12.25 mmol) in dichloromethane (84 mL) was added a solution of hydrogen chloride in 1,4-dioxane (28 mL, 4M). The reaction mixture was stirred at 30° C. for 2 h. The solvent was removed under reduced pressure to afford (R)-piperidine-3-carboxylic acid which was used without further purification.
