2-Cyano-4-methylpyridineCAS# 1620-76-4) Information
| Applicationem | 2-cyano-4-methylpyridine media organica est, quae primum oxidizari potest e 4-methylpyridine ad 4-Methyl-pyridinem-N-oxydatum praeparandum, ac deinde substitutum cum cyano globo obtinendum. 4-methyl-pyridine-N oxydatum praeparare potest 4-methyl -2, 6-dicarboxypyridine, 4-methyl -2, 6-dicarboxypyridine utilissima est pyridine derivativa et gravissima compositione media, quae late utatur. in agro pharmacopolio. |
| praeparatio | 4-methyl-pyridine-N-oxydi (0.109g,1mmol), trimethylcyanosilane (0.119g,1.2mmol), H-diethyl phosphite (0.276g,2mmol), tetrachloridum carbonii (0.308g,2mmol), triethylamine (0.202g; 2mmol) et acetonitrile 10mL in lenticula oris 50mL, agere ad locus temperatus pro 6h. Post reactionem peracta, solvendo sub pressura reducta removetur et per chromatographiam columnae separatur (acetatum petroleum aether/ethyl, V/V = 4:1) ut scopum liquidum sine colore compositum cum 80% cedat. |
