Reaction Steps
A mixture of 4.65 g (0.02 mole) ethyl 2-benzoyl-2-pentenoate and 3.56 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. Distillation of the crude product gave 4.25 g (92%) of ethyl 5-methyl-2-phenyl-3-furoate, bp 133°-135° C. (0.6 mm).
