First take an appropriate amount of 2- (4- (2- (2-amino-4-oxo-4,7-dihydro-3H-pyrrole And [2,3 - d] pyrimidine-5 - yl) ethyl) benzoic acid as a starting material, place it in a reactor, add an appropriate amount of ethylene diester reagents, and add a suitable catalyst, this catalyst can promote the condensation reaction between the two. During the reaction, attention should be paid to temperature control to maintain the temperature within a certain range to ensure the smooth progress of the reaction and prevent the formation of side reactions. After the reaction is completed, the product is purified by ordinary separation methods such as extraction, distillation, recrystallization, etc., to obtain (S) -diethyl 2- (4 - (2 - (2 - amino - 4 - oxo - 4,7 - dihydro - 3H - pyrrolo [2,3 - d] pyrimidine - 5 - yl) ethyl) benzamido) glutarate.
Then, the resulting esteride is mixed with 4-methylbenzenesulfonic acid in a certain molar ratio, an appropriate amount of organic solvent is added, and under suitable temperature and stirring conditions, the two undergo a salt-forming reaction. During this reaction process, the reaction process needs to be closely monitored, which can be measured by means of thin-layer chromatography. After the reaction is complete, the (S) -diethyl 2 - (4 - (2 - amino - 4 - oxo - 4,7 - dihydro - 3H - pyrrolido [2,3 - d] pyrimidine - 5 - yl) ethyl) benzamido) glutarate 4 - methylbenzene sulfonate can be obtained by filtration, washing, drying and other steps. The whole synthesis process must strictly abide by the operating procedures and pay attention to the control of each reaction condition to obtain the target product with high purity.

(S) -diethyl 2 - (4 - (2 - amino - 4 - oxo - 4,7 - dihydro - 3H - pyrrolido [2,3 - d] pyrimidine - 5 - yl) ethyl) benzamido) glutarate 4 - methylbenzene sulfonate, this is an organic compound. Its physical and chemical properties are quite important, related to its application in many fields.
First of all, the appearance is usually white to off-white crystalline powder, which is delicate and uniform. This appearance feature is easy to identify and make preliminary judgments. Looking at it like the first fall of snow, it is delicate and pure, making people know its texture at a glance.
In terms of solubility, it has a certain solubility in organic solvents such as methanol and ethanol, just like fish get water, which can be well dispersed. However, the solubility in water is relatively low, like a boulder entering water, it is difficult to completely dissolve. This difference in solubility is of great significance to the development of its formulations. The solubility in different solvents is different, which can affect the choice of drug formulations and dosage forms.
Melting point is also a key property. After determination, the melting point of the compound is in a specific range. This characteristic is like the "personality temperature" of the substance, which plays an extraordinary role in identification and purity detection. Accurate melting point data is like a key, which can open the door to the identification of compound purity and authenticity. In terms of stability,
is relatively stable in dry and cool environments. In case of high temperature, high humidity or strong light exposure, its structure and properties may change, just like a delicate flower in the event of strong winds and rain, it is easy to lose its original appearance. This stability feature needs to be considered during storage and transportation, and it is necessary to create a suitable environment for it to ensure its quality.
The above physical and chemical properties are of key value in the fields of drug research and development, chemical production, etc., and are the basis for in-depth understanding and rational application of this compound.
