実験手順

To the solution of 2-{[4-chloro-3-(trifluoromethyl)phenyl]oxy}-5-(hydroxymethyl)benzonitrile (500 mg, 1.526 mmol) in DCM (30 mL), was added thionyl chloride (1.671 mL, 22.89 mmol) dropwise. The mixture was stirred at room temperature for 2 h. After removing the solvent, the residue was dissolved in DCM, then washed with water twice, dried over Na2SO4, concentrated and purified via flash chromatography to afford the title compound (479 mg, 89% yield) as a white solid. LCMS: rt=3.45 min
