(2R,3R)-Benzyl 3-(tert-butoxycarbonylamino)-2-methylpiperidine-1-carboxylate (308) (1.7 g, 4.9 mmol) was dissolved in IPA (20 mL). 10% Pd/C (1 g) was added and the mixture was hydrogenated on a Parr shaker at 50 psi pressure for 12 hours. The reaction mixture was filtered through celite, and the solvent was removed under reduced pressure to give tert-butyl (2R,3R)-2-methylpiperidin-3-ylcarbamate (310), (1.1 g, 5.1 mmol, 100% yield).
