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. 19346-44-2, name is 2-Fluoro-3-nitro-5-methylpyridine, the common compound, a new synthetic route is introduced below. Application In Synthesis of 2-Fluoro-3-nitro-5-methylpyridine
3-Amino-2-fluoro-5-methylpyridine was prepared analogously from 2-fluoro-5-methyl-3-nitropyridine. This compound was obtained in 89 percent yield as white solid melting at 27-28.5 C. Elemental Analysis C6 H7 FN2 Calc.: %C, 57.1; %H, 5.59; %N, 22.2 Found: %C, 56.9; %H, 5.65; %N, 22.6 1 H NMR CDCl3: 7.2 (d, 1H); 6.8 (d, 1H); 3.7 (br, 2H); 2.1 (s, 3H); 13 C NMR CDCl3: 151.8 (d, J=229); 134.5 d, J=12.6); 132.2 (d, J=3.9); 129.9 (d, J=28.7); 125.8 (d, J=5.3), 17.8.
The synthetic route of 19346-44-2 has been constantly updated, and we look forward to future research findings.
