Reaction Steps

Stir (2R,5R)-5-[(1S,2S)-1-benzyloxy-2-dibenzylamino-3-(3,5-difluorophenyl)-propyl]-2-(2,2-dimethylpropoxy)-morpholine-4-carboxylic acid tert-butyl ester (0.1 g, 0.14 mmol) and 20% palladium hydroxide on carbon (0.1 g, 0.06 mmol, 60% moisture) in ethyl acetate (5 mL) under 1 atmosphere of hydrogen gas at room temperature overnight. Filter the suspension through a pad of filtering agent, wash with ethyl acetate and concentrate to give the title compound (0.06 g, 90%).
