The crude product from Example 2 was combined with 10 ml of 48% hydrobromic acid, and the resulting mixture was heated at its reflux temperature for one hour. Evaporation to dryness provided 6-aminomethyl-2(1H)-pyridone hydrobromide as a water-soluble solid. The structural assignment was supported by infrared and nuclear magnetic resonance spectral analyses.
