反応手順
6-Chlorophthalide (7.66 gms; 0.0452 mole), N-bromosuccinimide (8.1 gms; 0.0452 mole) and azobisbutyronitrile (0.1 gm) were gently refluxed in dry carbon tetrachloride (150 ml.) for 11/2 hours. On cooling, the succinimide was filtered off and the solvent removed in vacuo to leave a yellow solid, which was used immediately. Yield 9.57 gms. 86.2%
