Reaction Steps

A solution of 1,2-dibenzyl 3-tert-butyl(2S,3S)-5,5-difluoropiperidine-1,2,3-tricarboxylate (0.370 g, 0.000756 mol) in EtOH (7.0 mL) was hydrogenated in the presence of 10% Pd/C, under a ballon pressure of hydrogen, for 2 h. After filtered off the catalyst, the filtration was evaporated to dry. The residue was used directly in next step (190 mg, 94.77%). LC MS (M-Bu+1) 210.0.
