The synthetic route is as follows.
General procedure: A mixture of isatin derivatives 1 (1 mmol), 1-aryl-2-thiocyanatoethanone 2 (1 mmol) and Et3N (1mmol) in EtOAc (3 mL) was stirred at room temperature for 8 h. Then hydrazonoyl chloride 3 (1mmol) was added to the above mixture and the reaction was stirred at reflux temperature for 10min. After completion of the reaction, the reaction mixture was filtered, EtOAc was evaporated andthe residue was purified by recrystallization from ethanol to afford the pure product 4 in high yield.The two disterioisomers of products 4a-c were separated by washing the precipitate with n-Hexane/EtOAc (10/1)
The chemical industry reduces the impact on the environment during synthesis 5-Bromo-1-methylindoline-2,3-dione. I believe this compound will play a more active role in future production and life.
