Reaction Conditions:

with palladium 10% on activated carbon;hydrogen in methanol at 45; for 3 h;Cooling with ice;

Steps:

5 5. Preparation of (R) -piperidine-3-ylcarbamic acid tert-butyl ester:
In an ice bath, 247 g of (R)-(1-benzylpiperidin-3-yl) carbamic acid tert-butyl ester (851 mmmol), 2470 g of methanol and 5 g of palladium carbon (10 w%) were added to a three-necked reaction flask;Hydrogen was replaced 3 times, and then the system was raised to 45 ° C for 3h; the reaction was monitored by TLC.The system was cooled to room temperature, filtered, and the filtrate was concentrated to dryness to obtain 165 g of tert-butyl (R) -piperidin-3-ylcarbamate (purity 95%; yield 97%).
