Reaction Steps

The mixture of 3-fluoro-4-methoxybenzaldehyde (5.1 g, 33.0 mmol) and (carbethoxymethylene)triphenylphosphorane (17.2 g, 49.5 mmol) in anhydrous toluene (165 mL) was refluxed at 120° C. under nitrogen for 4 hours. The solvent was removed in vacuo and purified by silica gel chromatography (10-20% EtOAc in hexanes) to provide (E)-ethyl 3-(3-fluoro-4-methoxyphenyl)acrylate (537) (6.5 g, 87.6%) as a white solid.
