Reaktionsschritte
A mixture of 4,6-dimethyl2(1H)-pyridone (2.46 g., 0.02 moles), potassium hydroxide (1.58 g., 0.024 moles) and ethyl iodide (6.24 g., 0.04 moles) in 50 ml. ethanol is heated at reflux for 3 hours. The ethanol is removed under vacuum leaving a solid residue which is extracted with methylene chloride. The methylene chloride extracts are washed with 2.5 N sodium hydroxide, water, a saturated salt solution, and dried over sodium sulfate. Evaporation of the dried extracts affords 1-ethyl-4,6-dimethyl-2(1H)-pyridone as a pale yellow oil (1.5 g., 48%) which shows a single spot on thin layer chromatography.
