| Pengantar | 2-methoxy-4-methylpyridine is an organic intermediate, it can be prepared by nucleophilic substitution of 2-chloro-4-methylpyridine with sodium methoxide. |
| Penggunaan | 2-methoxy-4-methylpyridine is a heterocyclic organic compound that can be used as an organic intermediate. |
| persiapan | 2-chloro-4-methylpyridine (20g,0.156mol) and NaOCH3(9.3g,0.172mol) the mixture in DMSO (100 ml) was stirred at °c for 4 hours. The solution was added to H2O and then extracted with ethyl acetate (50ml x 2). The organic layer was washed with H2O (46% ml), brine (ml), and dried and concentrated to give 2-methoxy-4-methylpyridine (9g,). LC-MS:124[M + H]+,tR = 1.21 min. |
