p-Bromoacetophenone → 2-(4-Bromophenyl)propan-2-ol

참여 물질

반응 단계

Methyllithium (1.10 mol/l solution in diethyl ether, 502 mL, 0.552 mol) was added to a solution of 4-bromoacetophenone (100 g, 0.502 mol) in tetrahydrofuran (500 mL) in a nitrogen atmosphere at −78° C., and the mixture was stirred at the same temperature for one hour. The reaction mixture was poured into a saturated aqueous ammonium chloride solution, followed by extraction with ethyl acetate. The extract was washed with brine and dried over anhydrous magnesium sulfate, and the solvent was distilled off under reduced pressure to give crude 2-(4-bromo-phenyl)-propan-2-ol.
