Versuchsvorschrift

87.5 g of bromine are added dropwise at 25° C. over 3 hours to a solution of ethyl3-(4-methoxyphenyl)propanoate (113.9 g; 0.545 mol) in 900 ml of chloroform. The mixture is poured into water and the organic phase is separated out by settling of the phases and washed with 10% sodium hydrosulfite solution. After drying and evaporating off the solvents, a yellow oil is collected (154 g; 98%).
