Another approach is to prepare carboxylic acid derivatives containing pyrrole rings first, and then obtain the target product through a series of reactions such as reduction, methylation and esterification. Ethyl 2-pyrrolide is synthesized with suitable raw materials, and then methyl is introduced at the 4 position of pyrrole ring. This can be achieved by Grignard reagent reaction or nucleophilic substitution reaction. Prepare Grignard reagents and react with suitable halogenated hydrocarbons to introduce methyl.
In the process of synthesis, each step of the reaction needs to be strictly controlled by temperature and time, and appropriate reagents and reaction conditions are selected to achieve high yield and high purity of the target product. In this way, 4-methyl-2-pyrrolide ethyl ester can be synthesized efficiently.

4-Methyl-2-ethyl pyrrocarboxylate is one of the organic compounds. During storage and transportation, many matters need to be paid attention to.
Be the first to bear the brunt. When storing, be sure to choose a cool and dry place. Because if the environment is humid, water vapor is easy to interact with the compound, or cause it to undergo chemical reactions such as hydrolysis, which will damage its quality and purity. And a cool place can avoid the harm of high temperature, which can easily damage the stability of the compound, or cause adverse conditions such as decomposition.
Furthermore, this compound may have certain volatility and irritation, so the storage container must be well sealed. The sealing effect, one can prevent its volatilization and escape, and the other can avoid the mixing of external impurities to ensure the stability of its chemical properties.
During transportation, caution is also required. The compound should be properly fixed to prevent the container from breaking due to bumps and collisions. And the environment in the transportation vehicle should also be maintained stable to avoid drastic changes in temperature and humidity.
In addition, because 4-methyl-2-pyrrolitic acid ethyl ester or belongs to the category of hazardous chemicals, it must strictly follow relevant laws and standards when storing and transporting. Operators also need to have professional knowledge and skills, know the methods of emergency treatment, and in case of emergencies such as leaks, they can be disposed of in a timely and correct manner to prevent the harm from expanding. In this way, the safety and stability of 4-methyl-2-pyrrocarboxylate during storage and transportation can be ensured.
