Reaction Steps
A mixture of 5-bromo-4-ethyl-2-benzofuran-1(3H)-one (1.81 g, 7.51 mmol), potassium vinyltrifluoroborate (1.21 g, 9.01 mmol) and Pd(dppf)Cl2 (200 mg) in 20 mL of TEA and 20 mL of EtOH was heated to reflux under N2 overnight and then concentrated. The resulting oil was purified by column chromatography to give 4-ethyl-5-vinyl-2-benzofuran-1(3H)-one.
