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, 1796-84-5, blongs to pyridine-derivatives compound. Computed Properties of C7H8N2O3
Step 4: 1-N,N-Dimethylcarbamoyl-4-bromo-3-(4-(N-3-nitropyridin-4-yl)aminomethylbenzoyl)indole. A mixture of the 1-N,N-dimethylcarbamoyl-4-bromo-3-(4-aminomethylbenzoyl)indole prepared in step 3 (13.65 g) and 4-ethoxy-3-nitropyridine (5.10 g, 30.3 mmol) in CH3 CN (50 mL) was heated at reflux for 50 hours during which time 46 mL of solvent distilled out. To the thick residue was added toluene (50 mL) and the mixture was heated at a rate such that 21 mL of solvent distilled off over 2 hours. The reaction mixture was cooled to ambient temperature and diluted with ethyl acetate (30 mL). The solution was placed directly on a silica gel column and eluted with 50%, then 80% ethyl acetate/toluene to give 1-N,N-dimethylcarbamoyl-4-bromo-3-(4-(N-3-nitropyridin-4-yl)aminomethylbenzoyl)indole (6.76 g), mp 173.5-174.5 C. after crystallization from ethyl acetate/ether.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,1796-84-5, its application will become more common.
