実験手順: NBS (14.60 g) and AIBN (2.89 g) were added to a solution of the product from step (i) (9.85 g) in EtOAc (200 mL). The resulting mixture was stirred at 80° C. for 20 h. After cooling the mixture was washed with sat. sodium thiosulphate, brine, dried, filtered and the solvent removed. The crude product was purified using chromatography, to give the subtitle compound, 5.30 g. After cooling the mixture was washed with sat. sodium thiosulphate, brine dried filtered the solvent removed The crude product was purified

実験手順: 3-Bromomethyl-4-fluorobenzoic acid methyl ester (3.0 g, 12.1 mmol) was mixed with 4-iodophenol (3.2 g, 14.6 mmol) in acetone (75 mL) containing dry potassium carbonate (2.5 g, 18 mmol). The mixture was refluxed for 6 hrs and then filtered. The filtrate was concentrated and extracted with ether and water. The organic layer was dried over sodium sulfate and solvents were evaporated. The residue was purified through flash column chromatography (120 g silica gel, 0% to 20% ethyl acetate in hexanes over 40 minutes) to give clear oil as 4-fluoro-3-(4-iodophenoxy)methylbenzoic acid methyl ester (3.48 g, 74.4%). The mixture was refluxed for 6 hrs filtered The filtrate was concentrated extracted with ether and water The organic layer was dried over sodium sulfate and solvents were evaporated The residue was purified through flash column chromatography (120 g silica gel, 0% to 20% ethyl acetate in hexanes over 40 minutes)
