Ethyl (ethoxymethylene)cyanoacetate Usage And Synthesis

Chemical Properties

white to light yellow crystalline solid

Uses

Ethyl Cyano(ethoxymethylene)acetate is an intermediate in the synthesis of anti-inflammatory agents with gastroprotective effect in rats.

Synthesis

a) General procedure for the preparation of ethyl 4-(2-cyano-2-ethoxycarbonylvinylamino)benzoate: triethyl orthoformate (33.3 mL, 0.2 mol) was mixed with ethyl cyanoacetate (21.3 mL, 0.2 mol) in acetic acid anhydride (80 mL), and the mixture was heated for 5 hr at 150-160 °C. Upon completion of the reaction, it was cooled to room temperature and the solvent was removed by distillation under reduced pressure to give ethyl 2-cyano-3-ethoxyacrylate as a yellow solid (28.5 g, 84% yield).
