A mixture of (S)-benzyl 3-(4-methoxyphenyl)-2-((S)-2-(2-morpholinoacetamido)propanamido)propanoate (5.00 g, 10.4 mmol) and Pd/C (10%, 1.0 g) in THF (50 mL) was stirred under a hydrogen atmosphere for 2 h. The mixture was filtered and concentrated to afford (S)-3-(4-methoxyphenyl)-2-((S)-2-(2-morpholinoacetamido)propanamido)propanoic acid (3.3 g, 94% yield) as a colorless solid. 1H NMR (300 MHz, DMSO-d6): δ 8.24 (d, J=8.1 Hz, 1H), 7.76 (d, J=7.8 Hz, 1H), 7.13 (m, 2H), 6.82 (m, 2H), 4.35 (m, 2H), 3.71 (s, 3H), 3.63-3.56 (m, 4H), 2.99-2.65 (m, 4H), 2.41-2.38 (m, 4H), 1.20 (d, J=6.9 Hz, 3H). MS (EI) for C19H27N3O6, found 394.5 (MH+).
