Reaction Steps
To an ice-bath cooled, stirred solution of methyl 2-(2-fluorophenyl)acetate (3.4 g, 20 mmol) in THF (100 mL) was added NaH (1.8 g, 44 mmol). The reaction was stirred at 0° C. for 10 minutes and then dichloroethyl ether (2.7 mL, 22 mmol) and tetrabutylammonium bromide (0.33 g, 1.0 mmol) were added sequentially. The yellow reaction mixture was stirred for 16 hours at room temperature and then quenched with a saturated ammonium chloride solution. The aqueous layer was extracted with EtOAc (3×60 mL), and the organic layers were combined, dried (Na2SO4), filtered and concentrated to afford a yellow oil. Purification by flash chromatography (100% DCM) provided a pale yellow oil (2.5 g). MS m/e=239.0 (M+H)+.
