Reaktionsschritte
To a stirred mixture of phenylboronic acid (1.20 g, 9.85 mmol) and 4-bromo-2-methoxyphenol (1.00 g, 4.92 mmol) in DCM (50.00 mL) was added cupric acetate (1.34 g, 7.39 mmol), powdered 4 A molecular sieves and TEA (3.43 mL, 24.6 mmol) at rt. The resulting mixture was then stirred at rt for 24 h at ambient atmosphere. The solvent was then removed under reduced pressure and the resulting residue was purified by flash chromatography (5% EtOAc in Hexane). 1H NMR (400 MHz, MeOD) δ ppm 3.81 (s, 3H), 6.84-6.95 (m, 3H), 7.01-7.15 (m, 2H), 7.25-7.36 (m, 3H).
