Procedure

A mixture of 3-benzyloxycarbonylamino-6-methyl-1-(tert-butoxycarbonylmethyl)-2-pyridinone (4.1 g, 11 mmol), as prepared in the preceding step, and 10% Pd/C (400 mg) in ethanol (100 mL) was hydrogenated under hydrogen (balloon) for 1.5 h. The catalyst was removed by filtration through Celite and the filtrate concentrated to give the title compound as white solid (2.55 g, 97%). 1H-NMR (300 MHz, CDCl3) δ 6.49 (d, J=7.3 Hz, 1H), 5.92 (d, J=7.3 Hz, 1H), 4.75 (s, 2H), 2.19 (s, 3H), 1.47 (s, 9H).
