実験手順
6-Bromophthalide (5.85 gms; 0.0275 mole), N-bromosuccinimide (4.89 gm; 0.0275 mole) and azobisbutyronitrile (0.1 gm) were gently refluxed in dry carbon tetrachloride (200 ml.) for 2 hours. On cooling, the succinimide was filtered off and the solvent removed in vacuo to give an oil, which was used immediately.
