Versuchsvorschrift

To a solution of 3-fluoro-2-[[2-fluoro-5-(3-fluorophenyl)phenyl]methylamino]-6-methoxy-benzonitrile (560 mg, 1.5 mmol, 1 eq) in CH2Cl2 (30 mL) was added BBr3 (1.14 g, 4.5 mmol, 3 eq) and the reaction was stirred overnight. The mixture was then poured into water, and the aqueous layer was extracted with EtOAc. The combined organic extracts were washed with brine, dried (Na2SO4), filtered and evaporated in vacuo. The residue obtained was purified by column chromatography (petroleum ether:EtOAc, 10:1 to 5:1) to give the title compound as a yellow oil (360 mg, 68%).
