80 °C

To a mixture of 3-bromo-2-fluoro-phenol (2 g, 10 mmol) and cesium carbonate (10 g, 40 mmol) in acetonitrile (20 mL) was added 2-bromopropane (4 mL, 50 mmol). The reaction mixture was stirred at 80° C. for 4 h. The mixture was filtered through a plug of Celite and eluted with ethyl acetate. The resulting solution was evaporated. The residue was purified by flash chromatography on silica gel and eluting with hexanes:EtOAc (1:1) to afford the title product (1.7 g).
