Procedure

To (R)-1-(tert-butoxycarbonyl)piperidine-3-carboxylic acid (7.0 mmol) was added dichloromethane (48 mL) followed by hydrochloric acid (4M, 16 mL). 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.
