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. 13091-23-1, name is 4-Chloro-3-nitropyridine, the common compound, a new synthetic route is introduced below. Recommanded Product: 13091-23-1
Sodium carbonate (3.20 g, 30.27 mmol) and 4-fluorobenzylamine (2.14 ml, 18.92 mmol) were added to a solution of 4-chloro-3-nitropyridine (3.0 g, 18.92 mmol) prepared in Step 1 of Preparation 1 in 30 ml of anhydrous JV,./V-dimethylformamide and then the reaction mixture was stirred for 1 hour at 800C. The reaction mixture was diluted with a mixture of water (10 ml) and ethyl acetate (100 ml) and then washed with water (100 ml) twice. The separated organic layer was dried on anhydrous magnesium sulfate and then concentrated under reduced pressure to give the titled compound as a yellow solid (3.01 g, 83.5%).[63] 1 Eta-NMR (CDCl ) delta 8.60(s, 1Eta), 7.29(m, 3Eta), 7.18(m, 2H), 6.70(d, IH), 5.20(s,2H)
The synthetic route of 13091-23-1 has been constantly updated, and we look forward to future research findings.
