5-{2-[4-(1,2-Benzothiazol-3-Yl)Piperazin-1-Yl]Ethyl}-6-Chloro-1,3-Dihydro-2H-Indol-2-One Methanesulfonate Hydrate (1:1:3)

At a certain sunset, I was studying the wonders of chemistry in the quiet room. See a question: 5 - {2 - [4 - (1.2 - benzothiazole - 3 - yl) guanidine - 1 - yl]} - 6 - bromo - 1.3 - dioxo - 2H - pyran - 2 - carboxylic anhydride, and hydrate (1:1:3) What is the chemical structure?
I raised my eyebrows and thought deeply, this is the problem of analyzing the structure of organic chemistry. The ring system of benzothiazole has a unique conjugate structure and plays a key role in the molecule. It is connected to the guanidine group, and the basicity and reactivity of the guanidine group must affect the properties of the molecule as a whole. The introduction of bromine atoms may change the polarity and reaction check point of the molecule. Dioxypyran ring also has its special stability and reaction law.
The hydrate of this compound binds in a ratio of 1:1:3, and the water molecule interacts with the host molecule through hydrogen bonds. The position and binding mode of the water molecule are related to the polar group of the host molecule. In the host molecule, carbonyl, nitrogen atoms, etc. may be receptors of hydrogen bonds, forming hydrogen bonds with the hydrogen atom of the water molecule; and the oxygen atom of the water molecule may form hydrogen bonds with the active hydrogen atom in the molecule.
After some thought, I drew a sketch of its chemical structure. The main molecule is centered on benzothiazole, the guanidine group is properly substituted with the bromine atom, and the dioxypyran ring is cleverly connected to the carboxylic anhydride. The water molecules surround the main molecule and are arranged in an orderly manner through hydrogen bonds to form a unique three-dimensional structure. Although this is only a preliminary inference, the true meaning of chemistry can only be revealed through continuous exploration and verification.

The formula of this chemical is 5 - {2 - [4 - (1.2 - naphthalene anthracene - 3 - yl) nitrile - 1 - yl]} - 6 - bromo - 1.3 - dioxy - 2H - pyran - 2 - carboxybenzoic acid hydrate (1:1:3). This compound has several physical properties.
Its appearance or crystalline solid, due to the structure containing many aromatic rings and polar groups, the intermolecular force is strong, resulting in the formation of an ordered lattice structure.
In terms of solubility, in view of the non-polar parts such as naphthalene anthracene and pyran ring, it may have a certain solubility in non-polar organic solvents such as toluene and dichloromethane; it also contains polar groups such as nitrile group and carboxyl group, and it also has a certain solubility in polar organic solvents such as methanol and ethanol. However, due to the large size and complex structure of the molecule, the solubility in water may be limited.
The melting boiling point is quite high, due to the interaction of van der Waals force and hydrogen bond between molecules. Aromatic ring stacking and the interaction between polar groups require more energy to destroy the lattice, resulting in a higher melting point; strong intermolecular forces require more energy for gasification, and the boiling point increases accordingly.
In terms of stability, the aromatic ring in the structure has a conjugated system, which makes the compound stable to a certain extent. However, active groups such as nitrile and carboxyl groups cause structural changes under specific conditions such as strong acid, strong base or high temperature, or participate in chemical reactions.
Spectral properties are unique. Due to the large number of conjugated double bonds, there are significant absorption peaks in the ultraviolet-visible spectrum, which can be used for qualitative and quantitative analysis. In the infrared spectrum, each functional group has a corresponding characteristic absorption peak, which is helpful for structure identification.

To obtain 5 - {2 - [4 - (1.2 - anilinopyridine - 3 - yl) hydrazinyl - 1 - yl] ethyl} - 6 - chloro - 1,3 - diazo - 2H - indazole - 2 - carboxylic acid, hydrate (1:1:3), the method is as follows:
First take an appropriate amount of 1.2 - anilinopyridine - 3 - group and place it in a clean reactor. With a fine temperature control device, adjust the temperature in the kettle to a suitable range, generally about XX degrees Celsius. This temperature needs to be precisely adjusted according to the specific reaction characteristics, and there should be no slight deviation. Then, slowly add a certain amount of hydrazine-based reagent. When adding, the speed must be uniform and slow to prevent overreaction. After adding, continue to stir to make the two fully blend, and the reaction takes a period of time, about X hours.
After this step of the reaction is initially completed, the reaction product is moved to another reaction vessel, and a specific reactant is added to prepare 2- [4- (1.2-aniline-pyridine-3-yl) hydrazinyl-1-yl] ethyl moiety. This process requires strict control of the reaction conditions, including temperature, pressure, and the ratio of the reactants. The temperature should be maintained at about XX degrees Celsius, the pressure should also be stable at a specific value, and the ratio of the reactants should be precisely X: X. After several times of reaction, an intermediate product containing this group can be obtained.
Next, 6-chloro-1,3-dinitrogen-2H-indazole-2-carboxylic acid related reaction raw materials are introduced into this intermediate product. The reaction environment needs to be kept anhydrous and oxygen-free, and the method of inert gas protection can be used. In this environment, each reactant is fully reacted, and the reaction time is about X, and the temperature is controlled at XX degrees Celsius.
When the above reaction is nearly completed, the product is finely separated from the reaction mixture by specific separation and purification methods, such as column chromatography or recrystallization. Then, according to the ratio of 1:1:3, 5 - {2 - [4 - (1.2 - anilinopyridine - 3 - yl) hydrazinyl - 1 - yl] ethyl} - 6 - chloro - 1,3 - diazo - 2H - indazole - 2 - formic acid is combined with an appropriate amount of water to form a hydrate. When operating, be sure to accurately measure the amount of water to ensure that the ratio is correct. Through this series of fine operations, the required 5 - {2 - [4 - (1.2 - anilinopyridine - 3 - yl) hydrazinyl - 1 - yl] ethyl} - 6 - chloro - 1,3 - dinitrogen - 2H - indazole - 2 - carboxylic acid, hydrate (1:1:3) can be obtained. The whole preparation process requires the experimenter to have exquisite skills and rigorous attitude, and strictly control each reaction link to ensure the purity and yield of the product.
