実験手順: A solution of phenyl acetic acid (27.2 g.), benzyl alcohol (21.6 g.) and p-toluenesulfonic acid (380 mg.) in 100 ml. of toluene was heated under reflux under a Dean-Stark trap until the theoretical (3.6 ml.) quantity of water had been collected. On cooling, the solution was washed with dilute NaHCO3 and saturated NaCl and solvent was removed in vacuo. The resulting oil was distilled at 125°-129° (0.4 torr)1 to give pure benzyl phenylacetate, 37.7 g. (83% yield). ##STR229## had been collected On cooling the solution was washed with dilute NaHCO3 and saturated NaCl and solvent was removed in vacuo The resulting oil was distilled at 125°-129° (0.4 torr)1

実験手順: 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%. extracted with methylene chloride The organic layer is extracted again with 5% aqueous sodium hydrogen carbonate solution The aqueous extract extracted with ethyl acetate The organic layer is dried over sodium sulfate concentrated
