Reaction Steps

Stir (2R,3S,5R)-5-[(1S,2S)-2-acetylamino-3-(3-benzyloxy-5-fluoro-phenyl)-1-hydroxy-propyl]-2-(2,2-dimethyl-propoxy)-3-methyl-morpholine-4-carboxylic acid tert-butyl ester (0.81 g, 1.34 mmol) and 10% palladium on carbon (0.50 g, 1.41 mmol) in ethanol (20 mL) under a hydrogen atmosphere for 3 hours. Filter and concentrate to give 0.652 g (94.7%) of the desired compound as a white solid.
