Reaction Steps
A mixture of 5-bromo-7-fluoro-2-benzofuran-1(3H)-one (4.6 g, 20.0 mmol), potassium vinyltrifluoroborate (2.9 g, 22 mmol) and Pd(dppf)2Cl2 (0.5 g) in 40 mL of EtOH and 40 mL of TEA was refluxed under Ar for 4 hours. After concentration, the residue was purified by column chromatography (PE:EtOAc=20:1) to afford 7-fluoro-5-vinyl-2-benzofuran-1(3H)-one.
