18344-51-9, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 18344-51-9, name is 2-Amino-3-methyl-5-nitropyridine. This compound has unique chemical properties. The synthetic route is as follows.
To a solution of 3-methyl-5-nitropyridin-2-amine (1.0 g, 6.53 mmol) in DMF (30mL) was added cesium carbonate (3.2 g, 9.79 mmol) and Boc anhydride (4.5 mL, 19.59 mmol) followed by stirring at RT for 16 h. The mixture was diluted with EtOAc and washed with water. The organic layer was dried over sodium sulphate and concentratedunder reduced pressure. The residue was purified by combi-flash to afford the title compound as orange solid (0.7 g, 42 %). ?H NMR (400 MHz, DMSO-d6): oe 9.71 (s, 1H), 8.99 (d, J=2.4 Hz, 1H), 8.41 (d, J=2.0 Hz, 1H), 2.28 (s, 3H), 1.45 (s, 9H); LC-MS:mlz 252.2 (M-H).
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 18344-51-9, 2-Amino-3-methyl-5-nitropyridine.
