Use | for organic synthesis. |
production method | The pyridine is reacted with dimethyl sulfate to form a salt, potassium ferricyanide solution and sodium hydroxide solution are added, and the feeding temperature is not more than 10 ℃, 5h, the temperature rose to room temperature. The 1-methyl-2-pyridone was salted out from the reaction mixture by addition of anhydrous sodium carbonate with stirring. The deposited oil layer was separated to obtain a finished product in a yield of 65-70%. |
