Reaction Conditions

Reaction Steps

To 100 □ of 1,2-dichloroethane were added 5.5 □ of benzonitrile, 3.6 g of copper chloride and 11 g of potassium ethylmalonate, and then the mixture was stirred at reflux. After the reaction was completed, 100 □ of 6 N hydrochloric was added to the mixture, which then was stirred at reflux at 90° C. for 1 hour. After confirming completion of the reaction by TLC, the solution was cooled to 20° C., and then an organic layer was separated therefrom. The organic layer was concentrated through distillation under reduced pressure. Thus resulted residue was purified by silica gel column chromatography (eluent: ethylacetate/n-hexane=1/20, v/v) to obtain the title compound in the yield of 68% (7.0 g).
