Isatin derivatives exhibit significant biological, medicinal and pharmacological activities, [1,2] such as antituberculous, antihypoxing agent, anticonvulsant, antihyperglycemic; active against salmonella, typhi and against vibrio cholerae. Besides, they are used in treating and preventing pestvirus. [3] We describe in this work, the synthesis of new indoline derivatives.

To a solution of 1a-b (3.7 mmol) in 10 mL of ethanol, was added hydrazine hydrate (7.4 mmol). The mixture was refluxed for 6 h. After cooling the precipate was filtered and recrystallised from ethanol to afford product 2a-b.
