Hydrochloric Acid → Phenylacetic Acid

참여 물질

반응 단계

A mixture of benzyl phenylacetate (218 mg), methylene chloride (2 ml), aluminum chloride (357 mg), and nitromethane (1 ml) is stirred for 1 hour under ice cooling. The mixture is acidified with cold dilute hydrochloric acid and extracted with methylene chloride. The organic layer is extracted again with 5% aqueous sodium hydrogen carbonate solution. The aqueous extract is acidified with hydrochloric acid, and extracted with ethyl acetate. The organic layer is dried over sodium sulfate and concentrated to give phenylacetic acid (114 mg) melting at 77° C. Yield: 87%.
