Vorschrift

A mixture solution of 2-chloro-4-fluoro-6-methoxyquinoline (see U.S. 61/391,225 for synthesis) (280 mg, 1.32 mmol) and BBr3 (0.3 mL, 3.2 mmol, 2.64 g/mL) in DCM (5 mL) was stirred at 20° C. for 12 hours. Aqueous workup with DCM extraction gave the crude product, which was purified by silica gel column (PE/EtOAc=50/1) to give product (177 mg, yield 69%) as a white solid.
