Synthetic Route of 99365-40-9, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 99365-40-9, name is 6-Bromoindolin-2-one belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below.
General procedure: To a 25 mL round bottomed flask was added different substituted oxindoles 8 (0.2 mmol, 1.0 equiv.) and bromoethylsulfonium salt 9 (132.99 mg, 0.3 mmol, 1.5 equiv.), DMF (2 mL). The mixture was stirred at room temperature for 5min and Et3N (61.88 mg, 0.6 mmol, 3.0 equiv.) was added into reaction system. The mixture was stirred for 6h at room temperature until the reaction completed, quenched with saturated ammonium chloride solution (5 mL), and was extracted with EtOAc (3×30 mL). The combined organic layer washed with H2O (2×10 mL), dried with anhydrous sodium sulfate. After concentration, product was purified using column chromatography on silica gel with suitable eluent.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 6-Bromoindolin-2-one, other downstream synthetic routes, hurry up and to see.
