The general procedure described in Example 3 was used with 3,4-dimethyl-chlorobenzene (0.140 mL, 1.00 mmol), phenylboronic acid (157 mg, 1.20 mmol), Pd(OAc)2 (4.5 mg, 0.020 mmol, 2 mol %), sodium 2-dicyclohexylphosphino-2′,6′-dimethoxybiphenyl-3′-sulfonate (20.0 mg, 0.040 mmol, 4 mol %), K2CO3 (276 mg, 2.00 mmol), water (1.0 mL), 10 h, room temperature. The product was isolated as a colorless oil (151 mg, 99%). 1H NMR (400 MHz, CDCl3) δ: 7.82 (d, 2H, J=7.6 Hz), 6.81-7.55 (m, 6H), 2.24 (s, 6H).
