Ethyl benzoylacetate → Benzoylacetic acid

Participants

Reaction Steps

Sodium hydroxide (0.4 g) was dissolved in water (10 ml) and ethyl benzoylacetate (manufactured by Aldrich, 2.14 g: purity 90%) was added thereto and stirred at room temperature overnight. The reaction product was washed with ether and ether extraction was performed by adding a 10%-dilute sulfuric acid (4.9 g). An excess of anhydrous sodium sulfate was added to the ether extract, drying was performed thereon, and the anhydrous sodium sulfate was removed by filtering. In addition, the ether was removed using a rotary evaporator and a benzoylacetic acid was obtained (yield: 1.05 g).
