実験手順
4-Bromo-2-methoxy-5-methylphenol (500 mg, 0.002 mol), phenylboronic acid (0.70 g, 0.0058 mol), TEA (1.9 mL, 0.014 mol), cupric acetate (0.67 g, 0.0037 mol) and DCM (30 mL) were added to a 100 mL oven dried flask and the reaction mixture was stirred at rt for 48 h. Reaction mixture was then filtered through celite. The filtrate was concentrated in vacuo to give a residue which was purified by silica gel chromatography, eluting with 5% EtOAc in hexane. 1H NMR (400 MHz, CDCl3): δ=2.27 (s, 3H), 3.79 (s, 3H), 6.84 (s, 1H), 6.88-6.96 (m, 2H), 7.00-7.08 (m, 1H), 7.15 (s, 1H), 7.23-7.33 (m, 2H).
