실험 절차

To a stirred solution of 2-cyano-6-methylbenzoxazole (2.0 g, 12.66 mmol) in carbon tetrachloride (50 ml) at room temperature are added successively N-bromosuccinimide (2.37 g, 13.3 mmol) and benzoyl peroxide (30.7 mg, 0.13 mmol). The solution is irradiated with a sun-lamp for 2 hours and concentrated. The residue is dissolved in 500 ml of ether and the solution filtered. The filtrate is concentrated and subjected to HPLC (2% ethyl acetate in hexane) to afford 2-cyano-6-bromomethylbenzoxazole which is used directly in the next step.
