To a solution of 3-(3-chloro-phenoxy)-4-methoxy-phenyl]-methanol (13) (315 mg, 1.2 mmol) and triphenylphosphine (390 mg, 1.5 mmol) in methylene chloride (5 ml) was added NBS (0.250 mg, 1.4 mmol) in portions at 0° C. under nitrogen. After 10 min of stirring at 0° C., the mixture was allowed to warm to room temperature, and continued to stir for 16 h. After the solvent was removed, the residue was purified by silica gel column chromatography with ether/hexane as eluent to give 360 mg (85% yield) of product (14).
