Adding a certain compound to certain chemical reactions, such as: 19727-83-4, name is 6-Nitroindoline, belongs to indolines-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 19727-83-4, Recommanded Product: 6-Nitroindoline
At room temperature, 6-nitroindoline (99 mg, 0.6 mmol) was added to the reaction tube containing p-methylthiophenol (62 mg, 0.5 mmol) and dimethyl sulfoxide (1.0 mL). After stirring uniformly at room temperature, riboflavin 1 (0.025 mmol, 8 mg) and elemental iodine (0.05 mmol, 13 mg) were added in sequence, and then vacuum oxygen protection was applied. After the reaction tube was reacted at 60C for 24 hours, it was cooled to room temperature, and saturated sodium thiosulfate solution was added to quench the reaction. Then, the reaction solution was extracted with ethyl acetate, and then washed with saturated sodium chloride solution, and the organic layers were combined and dried with anhydrous sodium sulfate, and the organic layer was concentrated by rotary evaporation.Finally, it was purified by column chromatography (n-hexane: ethyl acetate = 30: 1) to obtain a yellow solid 6-nitro-3-(4-methylphenylthio)indole 106 mg, yield 75%.
