To a solution of methyl 3-formylbenzoate (2.00 g, 12.2 mmol) in tetrahydrofuran (20 mL) were added potassium carbonate (2.02 g, 14.6 mmol), diethyl(cyanomethyl)phosphonate (2.29 mL, 14.6 mmol) and water (0.4 mL), and the mixture was stirred at 60° C. for 1 hr. To the reaction mixture was added water (50 mL), and the mixture was extracted with ethyl acetate (50 mL, 20 mL). The combined organic layer was washed with saturated brine (10 mL), and dried over anhydrous sodium sulfate. The insoluble material was filtered off, and the filtrate was concentrated under reduced pressure to give methyl 3-(2-cyanoethenyl)benzoate as a white solid. The obtained compound was used for the next reaction without further purification.
