1,1-Dimethylethyl 4-azido-1-piperidinecarboxylate → 4-Amino-1-Boc-piperidine

Participants

Reaction Steps

A solution of 4.05 g (17.9 mmol) of 4-azido-1-t-butoxycarbonylpiperidine from Step A in 50 mL of methanol was hydrogenated with 350 mg of 10% Pd/C under a hydrogen balloon for 16 h when the reaction was complete by TLC (10% ethyl acetate/hexanes). The catalyst was filtered off and the volatiles removed in vacuo to give 3.5 g of title compound which was used directly in subsequent reactions.
