2-Cyano-4-methylpyridine (CAS# 1620-76-4) Zambiri
| Kugwiritsa ntchito | 2-cyano-4-methylpyridine ndi organic wapakatikati, yomwe ingakhale yoyamba oxidized kuchokera 4-methylpyridine kukonzekera 4-Methyl-pyridine-N-oxide, ndiyeno m'malo ndi cyano gulu kupeza. 4-methyl-pyridine-N-oxide angagwiritsidwe ntchito pokonzekera 4-methyl -2, 6-dicarboxypyridine, 4-methyl -2, 6-dicarboxypyridine ndi zothandiza kwambiri pyridine zotumphukira ndi yofunika kwambiri wapakatikati pawiri, amene ankagwiritsa ntchito. m'munda wa pharmacy. |
| kukonzekera | 4-methyl-pyridine-N-oxide (0.109g,1mmol), trimethylcyanosilane (0.119g,1.2mmol), H-diethyl phosphite (0.276g,2mmol), carbon tetrachloride (0.308g,2mmol), triethylamine (0.202g, 2mmol) ndi acetonitrile 10mL mu a 50mL botolo la pakamwa patatu, ikani kutentha kwa 6h. Pambuyo zimene anamaliza, zosungunulira ndi kuchotsedwa pansi kuthamanga yafupika ndi wolekanitsidwa ndi ndime chromatography (petroleum etha/ethyl acetate, V/V = 4:1) kupeza colorless madzi chandamale pawiri ndi 80% zokolola. |
