Versuchsvorschrift

To 5-hydroxymethyl-2-pyridone (114.9 mg, 0.9 mmol) was added 3.0 ml of 48% hydrobromic acid. The mixture was heated at 100° C. for 20 minutes. The excess hydrobromic acid was then evaporated in vacuo to give the corresponding 5-bromomethyl-2-pyridone. This compound was used without purification. HRMS: m/e, M+found; 186.9626, 7.4% Calc. for C6H6BrNO: 186.9633, −3.9 ppm.
