Water → 1-Bromo-2-fluoro-3-(phenylmethoxy)benzene

Participants

Reaction Steps

To a solution of 3-bromo-2-fluorophenol (1.8 g, 9.42 mmol) in acetone (25 ml) was added sodium carbonate (2.55 g, 20 mmol) and the mixture was stirred for 5 min. Benzylbromide (1.2 ml, 10.3 mmol) was added and the reaction mixture was heated at reflux for 20 h. Water (50 ml) and ethyl acetate (50 ml) was added and the phases were separated. The aqueous phase was extracted with ethyl acetate (2×50 ml) and the combined organic phases was dried (MgSO4) and evaporated under reduced pressure to give an oil. The residue was purified by flash column chromatography (isooctane/ethyl acetate, 5:1) to give the title compound (2.8 g). MS m/z (rel. intensity, 70 eV) 282 (M+, 2), 280 (M+, 2), 163 (2), 161 (2), 91 (bp).
