Reaction Steps

A solution of crude tert-butyl 2-((2S,3S)-3-{[(benzyloxy)carbonyl]-amino}-2-hydroxy-4-(3,5-difluorophenyl)butyl)-2-ethylhydrazinecarboxylate (906 mg, 1.8 mmol) in MeOH (15 mL) was added to 10% Pd/C (95 mg) and stirred in a hydrogen atmosphere (ambient pressure) for 4 h. The catalyst was filtered off over Celite and the filtrate was concentrated under reduced pressure to yield crude tert-butyl 2-((2S, 3S)-3-amino-2-hydroxy-4-(3,5difluorophenyl)butyl)-2-ethylhydrazinecarboxylate. MS (ESI+) for C17H27F2N3O3 m/z 360.2 (M+H)+.
