A mixture of 0.10 mole of 3-dimethylamino-1-(3-pyridinyl)-2-propen-1-one and 0.20 mole of p-toluenesulfonic acid in 150 ml of anhydrous ethanol was refluxed for 10 hours. The solvent was removed and the residue partitioned between water and dichloromethane. The organic layer was dried over magnesium sulfate and the solvent removed, giving 3-ethoxy-1-(3-pyridinyl)-2-propen-1-one.
