Reaction Steps

To a stirred solution of 3-ethylacetophenone (Maybridge Chemical Company Ltd.; 1.103 g, 7.44 mmol) in dry 1,4-dioxane (15 mL) was added bromine (383 μL, 7.44 mmol). The solution was stirred at room temperature for 30 min. and then the solvent was removed on a rotary evaporator. The residue was chromatographed on a Foxy 200 machine (Isco, Inc., P.O. Box 82531, Lincoln, Nebr. 68501, USA.; eluent, 5% CH2Cl2/Hexane, 0–2 min. then 20–30% CH2Cl2/Hexane, 2–20 min.) to give 2-bromo-1-(3-ethylphenyl)ethanone (1.15 g, 68%) as a clear oil.
