To a solution of 2-(2-fluoro-4-vinylphenoxy)-6-(trifluoromethyl)pyridine (0.342 mL, 1.554 mmol) in THF (10 mL) was added 9-BBN (4.66 mL, 2.330 mmol) at 0° C. The mixture was stirred at room temperature overnight, and quenched with water (2 mL), followed by aq. NaOH (3 M, 4 mL), and 30% H2O2 (5 mL). The reaction mixture was stirred at 50° C. for 2 h. Then the THF and some water 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, concentrated and purified by flash chromatography to afford the title compound (183 mg, 39.1% yield) as a colorless oil. LCMS: rt=2.45 min
