To a solution of 2,6-dichloro-N-[[2-fluoro-5-(3-fluorophenyl)phenyl]methyl]-3-methoxy-aniline (200 mg, 0.5 mmol, 1.0 eq) in DCM (15 mL) at 0° C. was added borontribromide (640 mg, 2.5 mmol, 5.0 eq) portion-wise. The reaction was stirred at room temperature overnight then poured into ice. The mixture was extracted with EtOAc and the combined organic extracts were dried, (Na2SO4) filtered and evaporated in vacuo. The residue obtained was purified by column chromatography (Petroleum ether:EtOAc, 20:1) to give the title compound (150 mg, 77%).
