실험 절차
A mixture of 3.56 g (0.02 mole) 3-acetyl-3-hepten-2-one and 3.55 g (0.02 mole) N-bromosuccinimide in 50 ml of carbon tetrachloride was heated at reflux for 2 hours. After cooling, the succinimide was removed by filtration and the solution concentrated in vacuo. Distillation of the crude product gave 3.04 g (86%) of 5-ethyl-2-methyl-3-furyl methyl ketone, bp 84°-87° C. (9 mm).
