4-bromotoluene, 171 mg (1 mmol), 2-methoxyphenylboronic acid, 152 mg (1 mmol), palladium diacetate, 1 mg (4 μmol), N-butylammonium bromide, 322 mg (1 mmol), and 2 M aqueous Na2CO3, 1.9 mL (3.8 mmol), were placed in a microwaveable pressure vial and heated to 150 C for 5 minutes. After cooling to room temperature, the product was poured into a separatory funnel and 30 mL each of water and diethyl ether were added. After extraction, the layers were separated and the aqueous layer washed with another 30 mL diethyl ether. The ether extracts were combined, dried over MgSO4, and the solvent removed by rotary evaporation under vacuum. 2-methoxy-4′-methylbiphenyl, 160 mg (81% yield) was obtained as a solid product, 95% purity by NMR.
