Prepare a solution of 5-methyl-2-phenyloxazole (790 mg, 4.97 mmol) in CCl4 (70 mL) under nitrogen. Add N-bromosuccinimide (884 mg, 4.97 mmol) and a catalytic amount of benzoyl peroxide. Reflux the mixture for 2 hours, cool to room temperature, and stir overnight. Wash the reaction mixture with a saturated solution of Na2SO3 (75 mL) followed by saturated sodium hydrogencarbonate (100 mL). Dry the organic phase (magnesium sulfate), filter, and concentrate to afford 1.17 g of 5-bromomethyl-2-phenyloxazole as a white solid. MS: m/e=238 (MH+)
