To a solution of (2S,3R)-benzyl 3-hydroxy-3-(4-methoxyphenyl)-2-((S)-2-(2-morpholino acetamido)propanamido)propanoate (2.0 g, 4.0 mmol) in THF (40 mL) was added Pd/C (500 mg, 10%). The mixture was stirred under a hydrogen atmosphere (1 atm) at ambient temperature overnight and then filtered through a pad of celite. The filtrate was concentrated under reduced pressure and the residue was washed with EtOAc (10 mL) to afford (2S,3R)-3-hydroxy-3-(4-methoxyphenyl)-2-((S)-2-(2-morpholinoacetamido)propanamido)propanoic acid (1.30 g, 78% yield) as a colorless solid.
