반응 단계
A mixture of 5-ethynyl-4-methyl-3-nitro-2-pyridone (0.18 g, 0.6 mmol) and 10% Pd/C (0.02 g) in ethanol/ethyl acetate (50 mL, 1/1) was hydrogenated at 35 psi in a Parr apparatus overnight. The catalyst was removed by filtration, and the solvents were evaporated to give 3-amino-5-ethyl-4-methyl-2-pyridone.
