Tetrahydrofuran → 3-(3-Bromophenyl)pentan-3-ol

Participants

Reaction Steps

Ethylmagnesium bromide (3 mol/l solution in diethyl ether, 34.1 mL, 102.3 mmol) was added to a solution of 3-bromobenzoic acid methyl ester (10 g, 46.51 mmol) in tetrahydrofuran (100 mL) in a nitrogen atmosphere at −78° C. The mixture was stirred at the same temperature for one hour and then heated to room temperature. The reaction mixture was poured into a saturated aqueous ammonium chloride solution, followed by extraction with ethyl acetate. The extract was washed with brine, dried over anhydrous magnesium sulfate and filtered, and the solvent was distilled off under reduced pressure to give crude 3-(3-bromo-phenyl)-pentan-3-ol.
