Procedure

A mixture of 2(S) methyl-2[3-benzyloxycarbonylamino-1,2-dihydro-2-oxo-1-pyridyl)propionate (49a) (2.75 g, 8.33 mmol), methanol (100 ml), and 10% palladium on carbon (300 mg) was stirred under an atmosphere of hydrogen for 30 min. The mixture was filtered and concentrated to afford 1.63 g (100%) of a colorless solid: 1H NMR (d6 -DMSO) δ 8.35 (1H, brs), 7.46 (1H, d), 7.22 (1H,d), 6.29 (1H, t), 5.22 (1H, q), 3.63 (3H, s), 1.55 (3H, d).
