To prepare N-Boc-prolyl-2-thiazolecarboxylate ethyl ester, there are various synthesis methods. One is to start with proline, and first react with Boc anhydride to obtain N-Boc-proline. This reaction requires a suitable temperature, and under the catalysis of alkali, the two are combined to make the amino group of proline get Boc protective group.
Then, N-Boc-proline interacts with sulfoxide chloride to convert into the corresponding acid chloride. In this process, the sulfoxide chloride converts the carboxyl group into an acid chloride group, and the reaction is relatively violent. It needs to be controlled at temperature and in an inert gas environment to prevent it from reacting with water vapor. < Br >
The obtained acid chloride is then reacted with 2-thiazolyl methanol in the presence of a base, and nucleophilic substitution is performed to form N-Boc-prolyl-2-thiazolyl methanol ester. Finally, the methanol ester is oxidized to ethyl ester with a suitable oxidant, such as Dyce-Martin oxidant, and the target product is obtained.
Another route is to use 2-thiazolyl methanol as the starting material, and first interact with a suitable activator to activate its carboxyl group. At the same time, after reacting proline with Boc anhydride to obtain N-Boc-proline, the two can undergo condensation reaction in the presence of condensing agents, such as carbodiimide condensing agents. The purpose of synthesizing N-Boc-prolyl-2-thiazolecarboxylate ethyl ester can also be achieved through multi-step operation. Each method has its own advantages and disadvantages, and the choice needs to be weighed according to the actual materials, equipment and reaction conditions.

When storing and transporting N-Boc-breast ammonia-2-carboxylate amidoguanidine salt, there are several ends to pay attention to.
When storing, the first environment is dry. If it is in a humid place, water vapor is easy to invade, or its properties may change and its effectiveness will be damaged. And it needs to be protected from light and cool. Strong light and high temperature can promote its chemical changes and reduce its stability. Furthermore, the storage place should be away from fire and heat sources. Because it may have certain chemical activity, it may be dangerous in case of fire or heat.
As for transportation, the packaging must be solid. Suitable containers are required to prevent it from leaking due to bumping and impact. And during transportation, the control of temperature and humidity is also the key. According to its physicochemical properties, the transportation method of temperature and humidity should be selected. If it is transported over long distances, it is necessary to regularly check the complete damage of the package to prevent accidents. All these are to ensure that N-Boc-breast ammonia-2-carboxylate amidoguanidine salt can preserve its inherent quality and avoid accidental changes between storage and transportation.
