ethyl 4-oxo-4-phenylbutanoate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 4-oxo-4-phenylbutanoic acid (5.00 g), ethanol (2.59 g), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (6.46 g), and 4-(dimethylamino)pyridine (171 mg) in N,N-dimethylformamide (25 mL) was stirred for 1.5 hours at room temperature. The mixture was partitioned between ethyl acetate (100 mL) and 1N hydrochloric acid (75 mL), and the organic layer was washed with water (75×3 mL), saturated sodium bicarbonate (75 mL), and brine (75 mL), dried over magnesium sulfate, and evaporated to give ethyl 4-oxo-4-phenylbutanoate as a colorless oil (4.19 g). The mixture was partitioned between ethyl acetate (100 mL) and 1N hydrochloric acid (75 mL) the organic layer was washed with water (75×3 mL), saturated sodium bicarbonate (75 mL), and brine (75 mL) dried over magnesium sulfate evaporated
