Reaction Conditions:
with NBS in N,N-dimethyl-formamide at 25; for 12 h;Inert atmosphere;
Steps:
4.1.2. General Procedure II: Synthesis of Multi-Substituted Isatin Derivatives (4a-4c)
General procedure: To a solution of compound 3 (3.0 mmol) in N, N-dimethylformamide (2.5 mL) wasadded NBS (3.3 mmol). The resulting reaction mixture was stirred at 25 C for 12 h. Afterthe reaction finished, the mixture was diluted with water (10 mL), the resultant precipitatefiltered, and the precipitate was dried in vacuo. The crude product was chromatographedgradiently on silica gel with PE/EA (10:14:1) to give the compounds 4a-4c.
