Aqueous sodium hydroxide (1M, 400 ml) was added to 2-bromo-(1S)-1-(4-bromophenyl)ethanol (77.0 g) in diethyl ether (400 ml) and stirred at room temperature for 5 hours. The organic layer was separated and aqueous layer was extracted with ether. The combined organic layer was washed with brine and dried over anhydrous sodium sulfate. Removal of the solvent yielded (2S)-2-(4-bromophenyl) oxirane (55.0 g) as a pale brown oil.
