Bromine → Ethyl 4-(2-bromoacetyl)benzoate

참여 물질

반응 단계

To a solution of ethyl 4-acetylbenzoate (5.12 g, 26.6 mmol) in ether (50 ml) containing aluminium chloride (0.025 g, 0.19 mmol) is added bromine (1.31 ml, 26.6 mmol) and the reaction mixture is stirred for 2 h. The reaction mixture is poured into saturated NaHCO3 solution and stirred for 30 min. and the layers are separated. The organic layer is washed with NaHCO3, H2O, dried over MgSO4, concentrated to half of its volume and refrigerated overnight. The resulting solid is filtered to yield ethyl 4-(2′-bromoacetyl)benzoate (5.89 g, 81.6%) as white crystals.
