실험 절차

A solution of bromine (1.84 ml) in ether (25 ml) was added dropwise over 1 hour at ambient temperature to a stirred solution of 3-(3,4-dichlorophenyl)-3-methylbutan-2-one (8.24 g) in ether (250 ml). After the addition was complete and the bromine colour had dissipated, the mixture was stirred at ambient temperature for a further 30 minutes then it was washed with water (100 ml), saturated aqueous sodium hydrogen carbonate solution (2×100 ml) and water (100 ml), dried (MgSO4), and the solvent removed in vacuo to give 1-bromo-3-(3,4-dichlorophenyl)-3 methylbutan-2-one as an oil (9.57 g) which was used without purification.
