To prepare 1H - pyrrole - 3 - carboxylic acid, 1 - (2 - hydroxyethyl) - 4 - methyl - 5 - [2 - (trifluoromethyl) phenyl] -, ethyl ester, the method is as follows:
First take 1 - (2 - hydroxyethyl) - 4 - methyl - 5 - [2 - (trifluoromethyl) phenyl] - 1H - pyrrole - 3 - carboxylic acid as the starting material. The raw material is placed in the reaction kettle, and an appropriate amount of ethanol is added as the reaction solvent. The amount of ethanol needs to be precisely prepared according to the amount of raw materials, so that the raw materials can be fully dissolved and conducive to the reaction.
Then, add an appropriate amount of catalyst, such as concentrated sulfuric acid or p-toluenesulfonic acid. This catalyst can accelerate the reaction process and improve the reaction efficiency. The amount of catalyst also needs to be carefully controlled. Too much or too little may affect the reaction effect.
When reacting, the reaction temperature needs to be precisely adjusted. Generally speaking, the temperature can be maintained in a certain range, such as 80-100 ° C. If the temperature is too high, it is easy to cause side reactions and the product is impure; if the temperature is too low, the reaction rate will be slow and take a long time.
During the reaction, the mixture is continuously stirred so that the raw materials, ethanol and catalyst are fully contacted and the reaction proceeds uniformly. After several hours of reaction, the reaction progress is monitored by thin-layer chromatography or other suitable analytical means until the raw materials are exhausted or the desired reaction degree is reached.
After the reaction is completed, the reaction mixture is cooled. Subsequently, the ethanol and other impurities in the reaction system are removed by appropriate separation methods, such as distillation and extraction. First, the ethanol is evaporated and recovered by distillation, using the difference between the boiling points of the ethanol and the product. After that, the extraction operation is carried out with a suitable extractant to enrich the product in the extraction phase.
Finally, the extracted product is purified. A suitable solvent can be selected by recrystallization, such as the mixed solvent of ethyl acetate and n-hexane, in which the product is recrystallized to remove residual impurities, and then obtain high-purity 1H-pyrrole-3-carboxylic acid, 1- (2-hydroxyethyl) -4-methyl-5- [2 - (trifluoromethyl) phenyl] -, ethyl ester products. The whole process must pay attention to the details of each step to control, in order to obtain satisfactory results.
