To prepare 5 - [ (tert - butoxycarbonyl) amino] pyridine - 3 - carboxylic acid, the following method can be followed.
The starting material can be selected from 3 - aminopyridine - 5 - carboxylic acid. Protecting the amino group first, and protecting the amino group with tert-butoxycarbonyl (Boc) is a common method. Take 3 - aminopyridine - 5 - carboxylic acid and dissolve it into a suitable organic solvent, such as dichloromethane, N, N - dimethylformamide (DMF), etc. After that, add a tert-butoxycarbonylation reagent, such as di-tert-butyl dicarbonate (Boc -2 O). In order to make the reaction smooth, an organic base such as triethylamine, N, N-diisopropyl ethylamine (DIPEA) can be added as a catalyst. The reaction temperature should be controlled between low temperature and room temperature. The reaction can be more selective at low temperature, such as starting at 0 ° C and gradually rising to room temperature. The reaction takes several hours. The reaction progress is monitored by thin-layer chromatography (TLC). When the raw material point disappears or the expected conversion rate is reached, the reaction can be recognized as complete.
After the reaction is completed, it can be post-treated according to the properties of the reaction system. If dichloromethane is used as the solvent, the reaction solution can be washed with dilute acid, water, and saturated salt water in sequence, dried with anhydrous sodium sulfate, and the solvent can be evaporated under reduced pressure The crude product can be purified by column chromatography, and the appropriate eluent is selected. According to the polarity of the product, such as eluting with petroleum ether-ethyl acetate system, the fraction containing the target product is collected, and the solvent is evaporated to obtain a pure 5- [ (tert-butoxycarbonyl) amino] pyridine-3-carboxylic acid.
Another way, if there are other suitable pyridine derivatives as starting materials, the synthesis of the target product can also be achieved by similar amino protection strategies and carboxyl group introduction or conversion steps. However, the reaction conditions and steps need to be adjusted in detail according to the structure of the starting material and the reactivity to achieve a good synthesis effect.

5 - [ (tert - butoxycarbonyl) amino acid] pyridine - 3 - carboxylic acid, which is a kind of organic compound. Its physical properties are quite important and are related to many chemical applications.
First of all, the appearance is often white to white solid powder. This form is easy to store and use. In many chemical reactions, the contact area between the powdered substance and other reagents is large, which is conducive to the full reaction.
Melting point is about 130 - 135 ° C. Melting point is the key physical constant of the substance, which can be used to judge its purity. If the purity of the substance is high, the melting point range is relatively narrow; if it contains impurities, the melting point will be reduced and the melting range will be widened. This is of great significance in the process of quality control and purification.
Solubility is also worthy of attention. The substance is slightly soluble in water, because although the carboxyl group in the molecule can form a hydrogen bond with water, the hydrophobic groups such as tert-butoxycarbonyl account for a large proportion, which makes it limited in solubility in water. However, it is soluble in common organic solvents such as dichloromethane, N, N-dimethylformamide (DMF), etc. In organic synthesis reactions, it is crucial to choose suitable solvents. These organic solvents can disperse the substance uniformly, providing a good environment for the reaction and promoting the smooth occurrence of the reaction.
In addition, the compound has certain stability. Under normal storage conditions, it can be stored in a dry and cool place for a period of time without significant decomposition. However, it is necessary to avoid contact with strong acids, bases, and other substances, as some functional groups in the molecular structure may react with them, thus altering the properties of the substance.
