Participants

Reaction Steps

A solution of 2-fluorobenzaldehyde (6.2 g, 50 mmol) and ethyl 2-(triphenylphosphoranylidene)butanoate (18.8 g, 50 mmol) in THF (200 mL) was refluxed for 2 hrs. The reaction mixture was concentrated and the residue was triturated with 1:1 hexane:ethyl acetate. The precipitate was removed by filtration through silica gel and the filtrate was concentrated. The residue was purified by chromatography on silica gel eluting with 8:2 hexane:ethyl acetate to give ethyl (E)-2-ethyl-3-(2-fluorophenyl)propenoate.
