実験手順
114 g (0.52 mol) of 6 and 103 g (0.58 mol) of N-bromosuccinimide were dissolved at room temperature in 2000 cm3 of carbon tetrachloride, admixed with 3 g of azobisisobutyronitrile and heated under reflux for 4 hours. The precipitated succinimide was filtered off, the solvent was removed under reduced pressure and the residue was purified by filtration through 1000 g of silica gel (hexane/methylene chloride 9:1). This gave 141 g (82%) of 7 as a colorless lacrymatory oil.
