Versuchsvorschrift

A suspension of 40.4 g (160 mmol) of the compound from Example XXXI in 400 ml of carbon tetrachloride, 31.3 g of N-bromosuccinimide (176 mmol) and 2.63 g of azobisiso-butyronitrile (16 mmol) is heated under reflux overnight. After cooling, the precipitate is filtered off with suction and washed with carbon tetrachloride. The combined filtrates are concentrated and the residue is further reacted in the crude state.
