Electric Literature of 693-98-1,Some common heterocyclic compound, 693-98-1, name is 2-Methyl-1H-imidazole, molecular formula is C4H6N2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
2-methyl-imidazole is reacted with a molar equivalent of acrylonitrile in a mixture of triethylamine and toluene. The mixture is heated at 50 C. to generate an intermediate imidazole compound linked to acrylonitrile, N-propanenitrile-2-methyl-imidazole. The nitrile bond is reduced by bubbling hydrogen gas into a solution of N-propanenitrile-2-methyl-imidazole in methanol catalyzed by Rainey Nickel. N-propylamine-2-imidazole is generated from the reduction reaction as seen in Scheme I.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2-Methyl-1H-imidazole, its application will become more common.
