Reaction Steps
4,5,6-Trimethoxyphthalide (11.4 gms; 0.05 mole), N-bromosuccinimide (8.9 gms; 0.05 mole) and azobisbutyronitrile (0.1 gms) were refluxed gently in dry carbon tetrachloride (200 mls) for 2 hours. The solution was cooled, the succinimide filtered off and the solvent removed in vacuo, leaving a yellowish solid which fumed in the air.
