Ethyl benzoylacetate → Benzoylacetic acid

Participants

Reaction Steps

To 11.6 g (60.3 mmol) of ethyl benzoylacetate, was added 60 mL of a 1 N aqueous sodium hydroxide solution, and the mixture was stirred at room temperature for 16 hours. After removing organic substances by ether, the reaction solution was acidified by adding concentrated hydrochloric acid while cooling the solution in an ice bath to give a precipitate. The precipitate was collected by filtration, washed with cold water, and dried under reduced pressure. As a result, 6.56 g (40.0 mmol, 66.3%) of benzoylacetic acid was obtained as a pale yellow powder.
