Reaction Steps

The mixture of 4-bromo-3-methyl-2-(methyloxy)benzonitrile (8.10 g, 35.8 mmol), potassium vinyl trifluoroborate (6.24 g, 46.6 mmol) and PdCl2(dppf)2 (0.55 g, 0.70 mmol) in 160 mL of EtOH and 40 mL of TEA was refluxed under Ar for 4 hours. The mixture was concentrated, and the residue was purified by column chromatography (PE:EtOAc=20:1) to afford 4-ethenyl-3-methyl-2-(methyloxy)benzonitrile.
