Reaction Steps

To a solution of methyl 4-(1-hydroxyethyl)benzoate (0.9 g, 5 mmol), 4-fluorophenol (627 mg, 5.6 mmol), triphenylphosphine (2.2 g, 8.4 mmol) in tetrahydrofuran (30 mL) was added diisopropyl azodicarboxylate (1.7 g, 8.4 mmol) at 0° C. The mixture was stirred at 20° C. for 12 hours. Water (15 mL) was added to the mixture and then extracted with ethyl acetate (35 mL×3). The combined organic phase was dried by sodium sulfate, and then filtered. The filtrate was concentrated in vacuo and the residue was purified by column chromatography (silica gel, petroleum ether/ethyl acetate=5:1) to give methyl 4-(1-(4-fluorophenoxy)ethyl)benzoate (490 mg, 35%).
