Adding a certain compound to certain chemical reactions, such as: 1796-84-5, 4-Ethoxy-3-nitropyridine, 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, SDS of cas: 1796-84-5, blongs to pyridine-derivatives compound. SDS of cas: 1796-84-5
Step 7: 3-[(4-(N-3-Nitropyrid-4-yl)aminomethyl)phenylsulfonyl]indole. A solution of 1-phenylsulfonyl-3-[(4-aminomethyl)phenylsulfonyl]indole (2.10 g, 4.79 mmol), prepared in step 6, and 4-ethoxy-3-nitropyridine (0.894 g, 5.31 mmol) in ethanol (20 mL) and triethylamine (1 mL) was heated at reflux for 70 hours. The reaction mixture was cooled to ambient temperature and diluted with ethyl acetate (250 mL). The organic phase was washed twice with H2 O and once with brine. The combined aqueous washings were extracted with ethyl acetate. The combined organic as layers were dried over Na2 SO4, filtered, and concentrated in vacuo. Chromatography on silica gel (ethyl acetate, then 0.2% ethanol/ethyl acetate) followed by recrystallization from ethyl acetate/ether gave 3-[(4-(N-3-nitropyrid-4-yl)aminomethyl)phenylsulfonyl]indole (350 mg, 23% yield). mp 97-102 C.
The synthetic route of 1796-84-5 has been constantly updated, and we look forward to future research findings.
