Versuchsvorschrift

A mixture of 6 g (0.029 mol) of ester obtained from step A, 5.6 g (0.031 mol) of N-bromosuccinimide and 100 mg of benzoyl peroxide in 100 ml of CCl4 is heated to reflux while irradiated with a sun-lamp, for 1 hour. The reaction mixture is cooled down and filtered to dryness to give ethyl 2-(2-bromomethylphenoxy)propionate which is used directly in the next step.
