참여 물질

반응 단계

A mixture of methyl sorbate (1.26 g, 10 mmol) and N-bromosuccinimide (1.98 g, 11.0 mmol) in chlorobenzene was irradiated with a 250 W sunlamp so as to achieve a state of reflux for 4 hours. The (cooled) mixture was then evaporated under reduced pressure to give a brown oil which was purified by column chromatography (9:1 60-80° C. petroleum ether:diethyl ether) to give the title compound (1.33 g, 65%) as a clear oil.
