Structurally, this molecule contains methyl, amino and carboxyl groups. The methyl group is the power supply group, which will affect the electron cloud density and chemical activity of the benzene ring, which can enhance the electron cloud density of the benzene ring and make the electrophilic substitution reaction of the benzene ring more likely to occur. The amino group is also the power supply group, which can significantly increase the electron cloud density of the benzene ring, especially at the ortho and para-positions. Therefore, the electrophilic substitution reaction on the benzene ring of 4-methyl-2-aminobenzoic acid is more likely to unfold in the ortho and para-positions of the amino group. The carboxyl group is an electron-withdrawing group, which will reduce the However, due to the conjugation of the carboxyl group with the benzene ring and the strong amino power supply effect, the overall electron cloud density of the benzene ring is still high.
In common chemical reactions, the carboxyl group can undergo esterification reaction, and it can form esters with alcohols under the catalysis of acid. For example, when catalyzed by concentrated sulfuric acid and heated with ethanol, 4-methyl-2-aminobenzoate ethyl ester and water will be formed. Amino groups are basic and can react with acids to form salts. For example, when reacted with hydrochloric acid, amino groups will combine hydrogen ions to form corresponding ammonium salts.

In this step, it is necessary to observe the reaction conditions, or use a catalyst, or adjust the temperature and pressure, so that the methyl groups are precisely attached to specific parts of hydrocarbons to form methyl-containing intermediates. Later, in a specific reaction environment, the intermediates interact with reagents containing amino groups and carboxyl groups. In this process, it is necessary to pay attention to the proportion of reagents and the process of the reaction, so that the amino group and the carboxyl group are cleverly combined to form the embryonic form of 4-methyl-2-pentyl glycine. After purification and refining, impurities are removed to obtain a pure product.
Second, there are other ways. Based on natural things, extract and transform. Find natural substances with similar structures, and separate and extract them to obtain relatively pure starting materials. Then, by chemical means, change its structure. Or break its old bonds, or form its new bonds, add methyl, amino, carboxyl and other functional groups. The key lies in knowing the characteristics of natural substances and the mechanism of each reaction, and precisely controlling them to achieve the goal.
Third, there is still a way. Use existing compounds to perform derivation methods. Select compounds with similar structures, use suitable reagents, and perform substitution, addition and other reactions according to specific reaction steps. For example, starting with a compound containing an amyl group, introduce carboxyl groups first, and skillfully adjust the reaction conditions to successfully connect the carboxyl groups. Then at the right time, introduce methyl and amino groups to gradually build the structure of 4-methyl-2-pentylglycine. This process requires careful study of each reaction step, so that each step can be carried out smoothly to obtain satisfactory results.
Although there are many methods of synthesis, it is necessary to be cautious, observe the details of the reaction, and study the changes in conditions in order to obtain this compound.
