Electric Literature of 104619-51-4,Some common heterocyclic compound, 104619-51-4, name is Di(1H-imidazol-1-yl)methanimine, molecular formula is C7H7N5, 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.
An oven-dried, round-bottomed flask was chargedwith di(lH-imidazoI-I-yl)methanimine (1.40 g, 8.69 mmol),2-amino-5-methylphenol (713 mg, 5.79 mmol) and anhydrous THF (20 ml) at ambient temperature. The resulting suspension was refluxed underN2 (g) for 2 h. The solvent wasremoved in vacuo and the residue was purified by silica gelchromatography (0-30% 9: I methanol:annnonium hydroxide-chloroform) to afford benzo[d]oxazol-2-amine (792 mg,5.35 mmol, 92% yield), as a grey solid.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route Di(1H-imidazol-1-yl)methanimine, its application will become more common.
