Procedure
In accordance with general method T, 4.70 g (24.00 mmol) of (1) are dissolved in 30 ml of carbon tetrachloride, with heating, and 5.00 g (28.00 mmol) of N-bromosuccinimide and 2 spatula tips of azobisisobutyronitrile are then added. The mixture is refluxed for 6 h with irradiation with a 500 W spotlight. On cooling to room temperature, succinimide separates out, and is filtered off. The filtrate is evaporated on a rotary evaporator in order to obtain the product as a yellow oil. Yield: 5.85 g (88.8%)
