What is the preparation method of ethyl 2- [3-bromo-4- (2-methylpropoxy) phenyl] -4-methyl-5-thiazole carboxylate

To prepare 2 - [3 - cyano - 4 - (2 - methylethoxy) phenyl] - 4 - methyl - 5 - pyrimidine carboxylate ethyl ester, the following method can be used.

First take an appropriate amount of starting materials, one is a benzene derivative containing a specific substituent, and the other is a pyrimidine-related compound. In the clean reactor, an organic solvent such as dichloromethane or N, N - dimethylformamide is placed to create a suitable reaction environment. < Br >
Put the raw material containing benzene ring into the kettle in proportion, stir well, and closely control the reaction temperature, generally maintained at a low temperature, about 0-10 ° C, to prevent the growth of side reactions. Then, slowly add the reactant containing the pyrimidine structure dropwise. This process needs to be carefully operated to ensure that the dropwise rate is uniform and stable, so that the two can fully contact and react.

Add it dropwise, gradually raise it to 30-50 ° C, continue to stir, and keep the temperature constant with the help of a temperature control device. During the reaction, take samples regularly, and monitor the reaction progress by thin-layer chromatography or high-performance liquid chromatography. When the raw material is converted to the expected degree, the reaction is terminated. < Br >
Then, pour the reaction solution into an appropriate amount of dilute acid solution, such as dilute hydrochloric acid, and perform quenching treatment to neutralize unreacted alkaline substances and precipitate the product. After liquid separation operation, collect the organic phase, and then wash it with saturated salt water several times to remove the remaining impurities and water.

Next, add an appropriate amount of desiccant to the organic phase, such as anhydrous sodium sulfate, and let it stand for a while to completely remove the residual water. After filtering to remove the desiccant, rotate and evaporate to remove the organic solvent to obtain a crude product.

The crude product needs to be further purified. Column chromatography can be used to separate and purify silica gel as the stationary phase, and petroleum ether and ethyl acetate are mixed as the mobile phase in an appropriate ratio. Collect the fraction containing the target product and concentrate it again to obtain pure 2- [3-cyano- 4- (2-methylethoxy) phenyl] - 4-methyl-5-pyrimidinecarboxylate ethyl ester. The whole process needs to strictly abide by the operating procedures and pay attention to the precise control of the reaction conditions to ensure the purity and yield of the product.
