Reaction Steps

A mixture of 2-cyanoethyl acetoacetate (5.00 g, 32.2 mmol), 1,4-benzodioxan-6-carboxaldehyde (5.29 g, 32.2 mmol), piperidine (137 mg, 1.61 mmol) and acetic acid (97 mg, 1.6 mmol) in 70 ml of 2-propanol was stirred at r.t. for 48 hrs. After evaporation of solvent, the product was purified by chromatography (SiO2, AcOEt: Hexane, 60:10). 2-[(3,4-Ethylenedioxyphenyl)methylene]-3-oxobutanoic acid 2-cyanoethyl ester was obtained as a yellowish oil (2.64 g, 27% yield).
