Reaction Steps
A mixture of 5-bromo-7-fluoro-4-methyl-3H-isobenzofuran-1-one (0.6 g, 2.45 mmol), potassium vinyltrifluoroborate (492 mg, 3.67 mmol) and Pd(dppf)Cl2 (100 mg) in 20 mL of TEA and 20 mL of EtOH was heated to reflux under N2 for 4 hrs and then concentrated. The resulting oil was purified by prep-TLC to give 7-fluoro-4-methyl-5-vinyl-3H-isobenzofuran-1-one.
