Procedure

To a suspension of 3,4-dichloro-3′-fluoro-4′-[4-(3-hydroxypropyl)phenoxy]benzanilide (2.32 g, 5.34 mmol) in dichloromethane (46 mL) were added carbon tetrabromide (2.13 g, 6.41 mmol) and triphenylphosphine (1.54 g, 5.88 mmol), and the resulting solution was stirred for 12 hours at room temperature. The reaction solution was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=5:1), to thereby yield 2.41 g of the title compound.
