Versuchsvorschrift
Bromine (4.6 ml) was dropped at 20-30° C. over 20 min. to a solution of methyl 3-propionyl-benzoate (17.24 g) in diethyl ether (0.15 L). Stirring was continued for 10 min. and the reaction mixture was then evaporated in vacuum to give methyl 3-(2-bromo-propionyl)-benzoate (25.5 g) as a yellow oil.
