2-Cyano-4-methylpyridine （CAS # 1620-76-4) Amakuru
| Gusaba | 2-cyano-4-methylpyridine ni intera ngengabihe, ishobora kubanza okiside kuva kuri 4-methylpyridine kugirango itegure 4-Methyl-pyridine-N-oxyde, hanyuma igasimbuzwa itsinda rya cyano kugirango ibone. 4-methyl-pyridine-N-oxide irashobora gukoreshwa mugutegura 4-methyl -2, 6-dicarboxypyridine, 4-methyl -2, 6-dicarboxypyridine ni inkomoko ya pyridine ningirakamaro cyane kandi ikoreshwa hagati, ikoreshwa cyane mu rwego rwa farumasi. |
| kwitegura | 4-methyl-pyridine-N-oxyde (0,109g, 1mmol), trimethylcyanosilane (0.119g, 1.2mmol), H-diethyl fosifite (0.276g, 2mmol), tetrachloride (0.308g, 2mmol), triethylamine (0.202g, 2mmol) na acetonitrile 10mL muri 50mL flask yiminwa itatu, reba ubushyuhe bwicyumba cya 6h. Nyuma yo kubyitwaramo birangiye, umusemburo ukurwaho munsi yumuvuduko ukabije hanyuma ugatandukanwa ninkingi ya chromatografiya (peteroli ether / Ethyl acetate, V / V = 4: 1) kugirango ibone intego yibintu bitagira ibara hamwe numusaruro wa 80%. |
Andika ubutumwa bwawe hano hanyuma utwohereze
