Procedure

4-Fluorophenylethyl bromide (700 mg, 3.44 mmol) was dissolved in toluene (4 mL), triphenylphosphine (904 mg, 3.44 mmol) added and the solution heated for 10 min in a sealed flask at 200° C. under microwave heating. After cooling to rt, the solvent was decanted and the title compound was obtained quantitatively as the remaining glassy solid, which was used without further purification.
