| Product | Ethyl 2-acetyl-4-bromo-2-pentenoate | HCID 54436818 | 98.2% |
Reaction Steps
A mixture of 8.06 g (0.047 mole) ethyl 2-acetyl-2-pentenoate and 8.43 g (0.047 mole) N-bromosuccinimide in 50 ml of carbon tetrachloride was heated at reflux for 15 minutes. The mixture was quickly cooled to room temperature, and the succinimide removed by filtration. Concentration of the solution in vacuo afforded 11.5 g (98%) of ethyl 2-acetyl-4-bromo-2-pentenoate.
