To prepare 2- (1-methylethyl) -1H-imidazole, the method is as follows:
First, a suitable starting material is obtained, usually a nitrogen-containing heterocyclic compound and a halogenated hydrocarbon with a specific substituent. If imidazole is selected as the initial nitrogen heterocycle, and isopropyl halogen (such as isopropyl bromide or isopropyl chloride) is used as the reagent for introducing 1-methylethyl.
In the reaction system, choose an appropriate solvent, such as N, N-dimethylformamide (DMF), dimethylsulfoxide (DMSO) and other polar aprotic solvents, such solvents can effectively dissolve the reactants and are beneficial to the reaction process. < Br > Add an appropriate amount of alkali, such as potassium carbonate, sodium carbonate, etc. The effect of alkali is to grab hydrogen from imidazole nitrogen atoms to form nitrogen negative ions, which have strong nucleophilicity; second, it can neutralize the hydrogen halide generated by the reaction, so that the reaction equilibrium moves in the direction of the product.
Temperature control allows the reaction to occur. Generally speaking, the reaction temperature is between 50 ° C and 100 ° C. If the temperature is too low, the reaction rate will be slow; if the temperature is too high, side reactions may occur. The reaction lasts for several hours, and the reaction process needs to be monitored by thin layer chromatography (TLC). When the raw material point almost disappears and the product point is clear and no longer changes, it can be regarded as the main reaction has been completed.
After the reaction is completed, pour the reaction liquid into an appropriate amount of water, and extract the product with an organic solvent such as ethyl acetate and dichloromethane. After separation, collect the organic phase, remove the water with a desiccant such as anhydrous sodium sulfate, filter the desiccant, and remove the organic solvent by decompression distillation to obtain a crude product.
The crude product still needs to be purified. It can be obtained by column chromatography, using silica gel as the fixed phase, and the mixed liquid of petroleum ether and ethyl acetate as the mobile phase. According to the difference between the polarity of the product and the impurity, it can be separated to obtain a pure 2- (1-methylethyl) -1H-imidazole.

Guanfu 2- (1-methylethyl) -1H-imidazole This substance is among the dangerous and has several hidden dangers.
This substance is flammable, in case of open flames and hot topics, it is very easy to burn, just like dry wood in case of fire, and instantly ignites a raging trend. In storage and transportation, if you don't pay attention, sparks will splash, which may cause a fire and cause harm to the surroundings. And when burning, harmful fumes may be released. The substances contained in this smoke may be toxic and harmful ingredients. If it invades the human body, through the way of breathing, it may hurt the lungs and damage health.
In addition, if it touches the skin, eyes and other parts, there is also a risk of irritation. If it accidentally touches the skin, it is like a sharp needle and a light prick, which can cause redness, itching, and even allergies to the skin; if it is not carefully entered into the eyes, it is like gravel into the eyes, and the tingling is unbearable.
