2-Cyano-4-methylpyridine (CAS# 1620-76-4) Macluumaad
| Codsiga | 2-cyano-4-methylpyridine waa dhexdhexaad dabiici ah, kaas oo marka hore laga soo saari karo 4-methylpyridine si loo diyaariyo 4-Methyl-pyridine-N-oxide, ka dibna lagu beddelo kooxda cyano si loo helo. 4-methyl-pyridine-N-oxide waxaa loo isticmaali karaa in lagu diyaariyo 4-methyl -2, 6-dicarboxypyridine, 4-methyl -2, 6-dicarboxypyridine waa pyridine derivative aad faa'iido u leh iyo xarun dhexe oo aad muhiim u ah, kaas oo si ballaaran loo isticmaalo. goobta farmashiyaha. |
| diyaarinta | 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) iyo acetonitrile 10ml oo ah a 50mL weel saddex-af ah, ku fal celi heerkulka qolka 6 saacadood. Ka dib marka falcelinta la dhammeeyo, dareeraha waxaa lagu saaraa cadaadis la dhimay waxaana lagu kala saaraa chromatography tiirka (petroleum ether/ethyl acetate, V/V = 4: 1) si loo helo bar-tilmaameed dareere ah oo aan midab lahayn oo leh 80% dhalid. |
