Reaktionsschritte

A solution of diethyl cyanomethylphosphonate (5.3 ml) in tetrahydrofuran (10 ml) was added dropwise to an ice-cooled mixture of sodium hydride (60%, 1.3 g) in tetrahydrofuran (40 ml). The mixture was stirred at 5° C. for 15 minutes. To the resulting mixture was added a solution of 4-(methylthio)benzaldehyde (5 g) in tetrahydrofuran (10 ml) at 5 to 10° C. The mixture was stirred at ambient temperature for 5 hours, diluted with ethyl acetate, and washed with water. The organic layer was dried and concentrated under reduced pressure. The residue was washed with a small amount of ether and dried to give pale brown crystals of 3-[4-(methylthio)phenyl]acrylonitrile (4.7 g).
