(3S,5S,6S)-5-[(hydroxyamino)carbonyl]-1-methyl-6-[(4-phenyl-3,6-dihydropyridin-1(2H)-yl)carbonyl]piperidin-3-yl pyrrolidine-1-carboxylate → (3S,5S,6S)-5-[(hydroxyamino)carbonyl]-1-methyl-6-[(4-phenylpiperidin-1-yl)carbonyl]piperidin-3-yl pyrrolidine-1-carboxylate

Participants

Reaction Steps

A solution of (3S,5S,6S)-5-[(hydroxyamino)carbonyl]-1-methyl-6-[(4-phenyl-3,6-dihydropyridin-1(2H)-yl)carbonyl]piperidin-3-yl pyrrolidine-1-carboxylate (5.0 mg, 0.000011 mol) TFA salt in 1 mL of MeOH was hydrogenated in the presence of 5% Pd/BaSO4, under a balloon pressure of hydrogen, for 2 h. After filtered off the catalyst, the filtration was concentrated to dry to give the product (5.0 mg, 100%). MS (ESI): (M+H)+=459.15.
