N-Bromosuccinimide (2.64 g) was added to a stirred suspension of 2-(1-cyclohexenyl)-4,5-diphenyloxazole (3.00 g) in dimethyl sulfoxide (20 ml) and water (267 mg) at room temperature and the resulting mixture was stirred at the same temperature for 19 hours. The reaction mixture was partitioned between ethyl acetate and water. The organic layer was separated, washed with water and brine, dried over sodium sulfate, and evaporated in vacuo. The residue was purified by column chromatography to afford 2-bromo-1-(4,5-diphenyl-2-oxazolyl)cyclohexanol (1.52 g) as a yellow solid.
