2-氨基-3-硝基-6-(4-氟苄基氨基)吡啶 | 2-amino-3-nitro-6-(p-fluoro-benzylamino)-pyridine | 33400-49-6 | C12H11FN4O2 | 262.243 |
A previously unknown dimer of the well-established analgesic flupirtine has been found, and its structure was revealed by ESI-MS, NMR spectroscopy and an independent synthesis. Thus, starting from 2-amino-6-chloro-3-nitro-pyridine the target compound was obtained in a four-step synthesis. Key-step of this synthesis is a nickel-mediated aryl-aryl coupling. The dimer 4 did not show any cytotoxicity, and its IC50 values were > 30 μm for all six human cancer cell lines and mouse fibroblasts used in this study
