Versuchsvorschrift
A mixture of 3.97 g (0.02 mole) ethyl 2-acetyl-5-methyl-2-hexenoate and 3.55 g (0.02 mole) N-bromosuccinimide in 50 ml of carbon tetrachloride was heated at reflux for 2.5 hours. After cooling, the succinimide was removed by filtration and the solution concentrated by rotary evaporation. Distillation of the crude product gave 3.33 g (85% ) of ethyl 5-isopropyl-2-methyl-3-furoate, bp 112°-114° C. (11 mm).
