To a solution of 3-bromo-5-methoxybenzoic acid (1 g, 4.06 mmol) and 2-chlorophenylboronic acid (1.27 g, 8.13 mmol) in 1,4-dioxane (10 mL) and water (2 mL), Pd(PPh3)4 (468 mg, 0.40 mmol) and Na2CO3 (2.15 g, 20.3 mmol) were added and the resulting mixture was stirred at 80° C. for 16 h. The mixture was allowed to cool to room temperature and acidified with aqueous HCl (1.0 M) to adjust the pH to 3-4. The mixture was extracted with ethyl acetate. The organic layer was dried over MgSO4, filtered and concentrated in vacuo to afford the desired product (800 mg, 75% yield) without further purification. ESI-MS m/z: 361.2 [M−H]−.
