3 - [di (tert - butoxycarbonyl) amino] - 6 - chloropyridine is an important compound in organic synthesis, and its synthesis method is as follows:
The starting material is often 6 - chloropyridine - 3 - amine. This compound reacts with di-tert-butyl dicarbonate under suitable reaction conditions, and di-tert-butyl dicarbonate acts as a donor of tert-butoxycarbonyl (Boc). The reaction is usually carried out in organic solvents such as dichloromethane, N, N - dimethylformamide (DMF).
In the reaction system, di-tert-butyl dicarbonate undergoes nucleophilic substitution reaction with 6 - chloropyridine - 3 - amine under the catalysis of an appropriate base. Commonly used bases can be triethylamine, N, N -diisopropyl ethylamine (DIPEA), etc. The function of the base is to activate the amino group of 6-chloropyridine-3-amine, which makes it easier to react with di-tert-butyl dicarbonate.

3- [di (tert-butoxycarbonyl) amino] -6-chloropyridine, which is an important compound in the field of organic synthesis. Its physical properties are unique and related to many practical applications.
Looking at its appearance, under room temperature and pressure, it mostly appears as a white to off-white solid powder. This form makes the substance relatively convenient to store and operate, and it is not easy to spill due to excessive fluidity.
In terms of melting point, it is usually in a specific temperature range, about [X] ° C. The characteristics of the melting point are of great significance for setting the reaction conditions during the synthesis process. When the temperature approaches or reaches the melting point, the state of the substance will gradually change from solid to liquid, which can affect the reaction rate and product purity. Knowing the melting point allows chemists to precisely control the reaction temperature and promote the reaction to progress in the desired direction.
Solubility is also a key physical property. In organic solvents such as dichloromethane, N, N-dimethylformamide (DMF), the compound exhibits good solubility. In dichloromethane, a uniform and stable solution can be formed, which is convenient for uniform dispersion as a reactant in organic synthesis reactions, so that the reaction can be fully carried out. However, the solubility in water is very poor, which is related to the hydrophobic groups contained in its molecular structure. This characteristic determines the choice of its reaction system and avoids operations that are not conducive to its dissolution and reaction in the aqueous phase system.
In addition, the compound has certain stability, but under extreme conditions such as strong acid, strong base or high temperature, the tert-butoxycarbonyl in the structure may change, affecting the overall chemical properties. Therefore, when storing and using, it should be properly stored in a cool, dry place away from strong acid and base substances.
