Synthetic Route of 288-32-4,Some common heterocyclic compound, 288-32-4, name is 1H-Imidazole, molecular formula is C3H4N2, 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.
General procedure: A 25 mL flask with a magnetic stirring bar was charged with CuI(9.6 mg, 0.05 mmol), metformin (0.1 mmol), Cs2CO3 (652 mg,2.0 mmol), imidazole (1.0 mmol), an aryl halide (1.1 mmol), andDMF (5 mL). The mixture was stirred for 10 min at room temperature,and then heated to 110?C for the appropriate amount of time(see Table 2). The progress of the reaction was monitored by TLC.After completion of the reaction, the mixture was extracted with EtOAc (5 1 mL) and the organic phase separated and evaporated. Further purification by column chromatography gave the desired coupled product.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 1H-Imidazole, its application will become more common.
