Application of 13505-01-6, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 13505-01-6, name is 3-Fluoro-4-nitropyridine. This compound has unique chemical properties. The synthetic route is as follows.
N-(4-Chloro-3-fluorophenyl)-4-nitropyridin-3-amine NaH (422 mg, 60% dispersion in mineral oil, 10.6 mmol) was suspended in THF (20 mL) and 4-chloro-3-fluoroaniline (1.54 g, 10.6 mmol) and 3-fluoro-4-nitropyridine (500 mg, 3.52 mmol) were added. The reaction mixture was stirred for 18 h, quenched with sat aq NH4Cl (2 mL), and concentrated in vacuo. The residue was partitioned between water (50 mL) and DCM (50 mL) and the organic fraction was dried (MgSO4) and concentrated in vacuo. The residue was purified by column chromatography to give the title compound (207 mg, 22.0%) as an orange solid. LCMS (ES+): 268.0 [MH]+.
According to the analysis of related databases, 13505-01-6, the application of this compound in the production field has become more and more popular.
