2-Cyano-4-methylpyridine (CAS# 1620-76-4) Information

Application 2-cyano-4-methylpyridine inonzi organic intermediate, iyo inogona kutanga yakasvibiswa kubva ku4-methylpyridine kugadzirira 4-Methyl-pyridine-N-oxide, uye inotsiviwa neboka recyano kuti riwane. 4-methyl-pyridine-N-oxide inogona kushandiswa kugadzira 4-methyl -2, 6-dicarboxypyridine, 4-methyl -2, 6-dicarboxypyridine inobatsira zvikuru pyridine derivative uye yakakosha zvikuru yepakati musanganiswa, iyo inoshandiswa zvakanyanya. mumunda we pharmacy.
kugadzirira 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) uye acetonitrile 10mL mu a 50mL katatu-muromo furasiki, pindura pakamuri tembiricha kwe6h. Mushure mekuita kwapera, mushonga unobviswa pasi pekumanikidzwa kwakaderedzwa uye kuparadzaniswa nekoromo chromatography (petroleum ether / ethyl acetate, V / V = ​​4: 1) kuwana mvura isina ruvara inotarirwa musanganiswa ne 80% goho.
