反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A solution of 2,4-dichlorophenylacetonitrile (30.00 gms, 161 mmol) (Aldrich) in dry ethyl acetate (36 ml) was added dropwise to an ethanolic solution of sodium ethoxide, prepared in situ from sodium metal (4.90 g, 213 mmol) and dry ethanol (60 ml). This reaction mixture was refluxed for two hours, allowed-to stand overnight at room temperature and the ethanol was evaporated. The yellow solid obtained was dissolved in water and the resulting solution was extracted twice with ether. The aqueous layer was chilled and acidified with hydrochloric acid. The crude product was extracted with ether to give 23.31 g of white solid. This reaction mixture was refluxed for two hours the ethanol was evaporated The yellow solid obtained the resulting solution was extracted twice with ether The aqueous layer was chilled The crude product was extracted with ether
