Reaktionsschritte
Into a 500-mL round-bottom flask was placed CH3COCH3 (200 mL), 2-bromophenol (10.38 g, 60.00 mmol, 1.00 equiv), iodoethane (28.08 g, 180.04 mmol, 3.00 equiv) and potassium carbonate (33.12 g, 239.64 mmol, 3.99 equiv). The resulting solution was heated to reflux overnight in an oil bath. The solids were filtered out. The filtrate was concentrated under vacuum. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:100). Purification afforded 11.48 g (95%) of 1-bromo-2-ethoxybenzene as a colorless oil.
