Synthetic Route of 611-09-6, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 611-09-6, name is 5-Nitroindoline-2,3-dione, This compound has unique chemical properties. The synthetic route is as follows.
Intermediate 2 (200 mg, 1.04 mmol), neopentyl glycol (108 mg, 1.04 mmol), p-toluenesulfonic acid (25 mg, 145 mumol) were added to cyclohexane (10 ml), a water separator of the reaction device and a reflux condenser The reaction was refluxed for 16 h. The reaction produced a white solid insoluble in cyclohexane. The reaction was detected by TLC. The solid product was filtered, the solid product was washed with water, dried, and then subjected to silica gel column chromatography (petroleum ether: ethyl acetate = 5: 1). The product was recrystallized from acetonitrile to obtain 243 mg of white needle crystals. Yield: 84%.
The chemical industry reduces the impact on the environment during synthesis 5-Nitroindoline-2,3-dione. I believe this compound will play a more active role in future production and life.
