Procedure

To the solution of 1-chloro-4-[(4-ethenylphenyl)oxy]-2-methylbenzene (2.46 g, 10.05 mmol) in dry THF (30 mL), was added 9-BBN (30.2 mL, 15.08 mmol) at 0° C. The mixture was stirred at room temperature overnight, and quenched with water (3 mL), followed by aq. NaOH (13.00 mL, 39.0 mmol), and 30% H2O2 (13.00 mL, 126 mmol). The reaction mixture was heated at 50° C. for 3 h. Then THF was removed under reduced pressure, and the residue was diluted with EA. The organic layer was washed with water and brine, dried over anhydrous Na2SO4 and concentrated and purified by flash chromatography to afford the title compound (1.13 g, 42.8% yield) as colorless oil. LCMS: rt=3.49 min, [M+H+]=245
