Reaction Steps

A mixture of 3-fluorophenol (6.00 g, 53.5 mmol), ethyl 4-bromobutanoate (15.70 g, 80.5 mmol) and Cs2CO3 (26.20 g, 80.4 mmol) in DMF (25 mL) under N2 was refluxed overnight. The mixture was then cooled to rt and 150 mL of water was added. The resulting mixture was extracted with DCM (100 mL×2) and the combined organic phases were washed with brine (100 mL×2), dried over anhydrous Na2SO4 and concentrated in vacuo. The residue was purified by a silica gel column chromatography (PE/EtOAc (V/V)=10:1) to give the title compound as colorless oil (12.0 g, 99%).
