반응 단계
A mixture of 3.41 g (0.02 mole) ethyl 2-acetyl-2-pentenoate and 3.57 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 gave 2.8 g (83%) of ethyl 2,5-dimethyl-3-furoate, bp 96 °-100° C. (18 mm).
