Procedure

A mixture of 5-bromo-2-methylphenol (1.0 g), phenylboronic acid (1.30 g), Cu(OAc)2 (0.97 g), and triethylamine (2.98 mL) in dichloromethane (50 mL) was stirred for 4 days. The mixture was diluted with ethyl acetate, washed four times with 1M aqueous NaOH solution and once with brine, dried over Na2SO4, filtered, and concentrated. The crude product was chromatographed on silica gel using 2% ethyl acetate in hexanes to afford the title compound.
