288-32-4, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 288-32-4 name is 1H-Imidazole, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
To a solution of N-H heterocycle (1 mmol) and aryl halide (2 mmol) in toluene were added catalyst (0.07 g, 0.016 mmol) and K2CO3 (276 g, 2 mmol) and the mixture stirred at 110 C for the specified time. The progress of the reaction was monitored by TLC. The reaction mixture allowed cooling to room temperature and ethyl acetate (25 mL) was added and the mixture stirred for 15 min to ensure product removal from catalyst. Then the catalyst was filtered, washed with ethyl acetate (2 9 25 mL). The organic layer was evaporated under vacuum on a rotary evaporator and the crude product was obtained. Further purification was achieved by column chromatography using ethyl acetate/n-hexane gradient. Structural assignments of the products are based on their 1H NMR and melting point.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 1H-Imidazole, and friends who are interested can also refer to it.
