Reaction Steps
To a stirred solution of 4-methyl-3-nitro-2-pyridone (0.45 g, 2.9 mmol) in glacial acetic acid (3 mL) was added sodium acetate (0.24 g) followed by bromine (0.15 mL) dropwise. After 5.5 hours, the mixture was diluted with ethyl acetate, washed with water, dried, filtered and concentrated to give 5-bromo-4-methyl-3-nitro-2-pyridone (0.62 g, 2.6 mmol, 90%).
