To prepare 1- [tert-butyl (dimethyl) silyl] -1H-imidazole, the method is as follows:
First take imidazole as the starting material, because the imidazole ring has active hydrogen, it can react with reagents containing tert-butyl (dimethyl) silyl. Tert-butyl (dimethyl) chlorosilane (TBDMS-Cl) is commonly selected as the reagent for introducing tert-butyl (dimethyl) silyl.
In a suitable reaction vessel, an anhydrous organic solvent such as dichloromethane, N, N-dimethylformamide (DMF) is used as the reaction medium. Among them, dichloromethane has good solubility and volatility, while DMF has good solubility to the reaction substrate and product, and can promote the reaction.
Dissolve imidazole in the selected organic solvent, at low temperature, such as 0 ° C to 5 ° C, slowly add tert-butyl dimethylchlorosilane dropwise, and add an organic base, such as triethylamine or imidazole itself (because it is also basic). The effect of alkali is to neutralize the hydrogen chloride generated by the reaction and promote the positive progress of the reaction. Triethylamine is moderately basic and can effectively bind hydrogen chloride to form corresponding salts.
Add it dropwise, raise it to room temperature or appropriate temperature, and continue to stir the reaction. This process takes a number of times, depending on the specific conditions of the reaction, or several hours or even ten hours. During this period, the reaction process can be monitored by thin-layer chromatography (TLC) to observe the consumption of raw materials and the formation of products.
When the reaction is completed, the reaction is quenched with water to remove the unreacted tert-butyl dimethyl chlorosilane and the generated salts. The product is extracted with an organic solvent, such as dichloromethane, ethyl acetate, etc. The organic phases are combined and dried with anhydrous sodium sulfate or magnesium sulfate to remove the moisture in the organic phase.
Then, the organic solvent is removed by reduced pressure distillation to obtain a crude product. The crude product was purified by column chromatography, and a suitable eluent was selected, such as the mixed solvent of petroleum ether and ethyl acetate. According to the polarity difference between the product and the impurity, pure 1- [tert-butyl (dimethyl) silyl] -1H-imidazole was separated.

1 - [tert - butyl (dimethyl) silyl] - 1H - imidazole is a commonly used reagent in organic synthesis. During storage and transportation, many matters need to be paid attention to.
First, when storing, it must choose a dry and cool place. This reagent is easy to hydrolyze in contact with water, and the presence of water can cause its structure to be damaged, thereby damaging its activity. Therefore, in the warehouse, the humidity should be controlled at a low level, and the temperature should not be too high to prevent it from deteriorating.
Second, because it has a certain chemical activity, it should be stored separately from oxidizing agents, acids, bases and other substances. Oxidizing agents can lead to oxidation, and acids and bases may cause chemical reactions to occur and change their chemical properties.
Third, the packaging must be tight. Good packaging can isolate air and moisture and prevent external factors from affecting it. Commonly used packaging materials should have good sealing and corrosion resistance.
As for transportation, it is necessary to ensure its stability. Vibration, collision or temperature changes during transportation may all have adverse effects on it. Therefore, the transportation vehicle should be equipped with stable fixtures and adjust the temperature to avoid excessive fluctuations.
In addition, transportation and storage personnel need to be professionally trained to be familiar with the characteristics and safety precautions of the reagent. In the event of an accident such as a leak, effective emergency measures should be taken quickly to reduce the hazard. In this way, the safety and quality of 1- [tert - butyl (dimethyl) silyl] -1H - imidazole during storage and transportation are guaranteed.
