A mixture of 1-(4-methoxybenzyl)-4-methyl-3-nitro-2-pyridone (1.5 g, 5.5 mmol) and 10% Pd/C (0.15 g) in ethanol (150 mL) was hydrogenated at 40 psi in a Parr apparatus for 5.5 hours. The catalyst was removed by filtration, and the solvent was evaporated to give 3-amino-1-(4-methoxybenzyl)-4-methyl-2-pyridone (1.3 g, 5.3 mmol, 96%).
