実験手順

To a solution of 3′-fluoro-4′-methoxyacetophenone (1 g, 5.9 mmol) (Aldrich) in dioxane (10 mL) was added dropwise a solution of bromine (1.13 g, 7.1 mmol) in dioxane (30 mL). After stirring for 10 minutes, the mixture was concentrated in vacuo and the residue was purified by flash chromatography, with 10:4 hexanes/dichloromethane as an eluant, to provide 2-bromo-1-(3-fluoro-4-methoxyphenyl)ethanone as a white powder (910 mg, 63% yield).
