反応手順
A mixture containing 68.7 g. (0.19 mole) of 2,7-dibromo-5-methyl-3-phenylbenzofuran and 35.5 g. (0.19 mole) of N-bromosuccinimide in one liter of carbon tetrachloride is irradiated with a bulb simulating sunlight for two hours. An additional 10 g. of N-bromosuccinimide is added, and irradiation is continued for one hour. The mixture is cooled and filtered. The filtrate is evaporated to a brown oil which crystallizes when triturated with hexane to provide solid 5-bromomethyl-2,7-dibromo-3-phenylbenzofuran.
