실험 절차

Dissolved 1-(5-fluoro-2-hydroxyphenyl)ethanone (10.0 g, 64.9 mmol) in 18 mL 1,2-Dibromoethane and added Potassium carbonate (18.8 g, 136 mmol) and 100 mL 2-Butanone. Heated the reaction mixture to reflux and allowed to stir overnight under nitrogen. Reaction was complete by LCMS. Diluted reaction mixture with water and extracted the product with ethyl acetate. Concentrated in vacuo and purified by flash chromatography (0 to 30% ethyl acetate/heptanes) to give 3.71 g (21.9% yield) of 1-(2-(2-bromoethoxy)-5-fluorophenyl)ethanone.
