To a solution of 2-fluoro-4-(2-hydroxyethyl)phenol (22.41 mmol, 3.5 g) and (4-chloro-3-fluorophenyl)boronic acid (45 mmol, 7.82 g) in dry CH2Cl2 (150 mL) were added copper (II) acetate (4.5 mmol 0.81 g), pyridine (45 mmol, 3.55 g), and 4 A molecular sieves in turn. The mixture was stirred at room temperature under N2 for 72 hours. The reaction mixture was filtered and the filtrate was concentrated to give crude product. The crude product was purified by silica gel chromatography to provide the desired product (1.4 g, 20%).
