Versuchsvorschrift

A solution of 4-pyridylacetic acid in 500 ml of anhydrous ethanol containing 75 ml of concentrated sulfuric acid is refluxed 18 hours. The solution is cooled to 0° an neutralized by addition of sodium hydroxide solution and saturated aqueous sodium carbonate. Extraction with ethyl acetate yields on concentration in vacuo ethyl 4-pyridylacetate.
