A solution of 4-(benzyloxy)-3,5-difluorobenzaldehyde (7) (1.32 g, 5.34 mmol) and (1-ethoxycarbonylethylidene)triphenyl phosphorane (2.32 g, 6.41 mmol) in tetrahydrofuran (53 mL) was refluxed for 2 hours. The reaction was concentrated in vacuo and was purified by flash column chromatography (0-100% EtOAc in hexanes) to give (E)-ethyl 3-(4-(benzyloxy)-3,5-difluorophenyl)-2-methylacrylate (8).
