الإجراء التجريبي
Into a solution of potassium salt of 3-oxo-2-cyanopropanoic acid ethyl ester (1.79 g, 10 mmol) in water (10 ml) was added a 50% solution of triphenylsulfonium chloride in water (5.96 g, 10 mmol). The reaction mixture turned cloudy. Water (15 ml) was added and the mixture was extracted with chloroform (2×25 ml) followed by drying over MgSO4. The removal of the solvent on a rotary evaporator under reduced pressure gave desired product as yellow crystalline material. Yield 3.2 g (80%).
