참여 물질

반응 단계

A solution of 1-benzyl-4-tertbutyloxycarbonylaminomethylpiperidine 8 (4.79 g; 15.7 mmol) in 120 ml of MeOH is poured into a hydrogenation reactor. The 10% Pd/C-based catalyst is added (0.872 g; 0.82 mmol) and the mixture is subjected to a hydrogen pressure of 3.5 bars (50 psi) for 24 hours in a Parr type shaker. After filtration on celite and washing with methanol, the medium is concentrated in order to produce 3.36 g (Yield=100%) of product in the form of white crystals.
