I will explain it in the form of ancient Chinese.
2- [ (6-cyano-2-methyl-4-pyridyl) amino] -5 -fluorobenzamide, this is an organic compound. Its physical properties are quite important, related to its use and reaction characteristics.
Looking at its physical state, it is mostly solid at room temperature and pressure. Due to the strong intermolecular forces, it has a relatively stable structure and can maintain a solid state. The melting point of this compound also has characteristics. The melting point is related to the lattice energy of the molecule. The larger the lattice energy, the higher the melting point. The intermolecular forces of this compound, including van der Waals forces and hydrogen bonds, work together on the lattice energy, causing its melting point to be in a specific range. The boiling point is related to the energy required to overcome the intermolecular forces and turn it into a gaseous state.
Furthermore, solubility is also an important physical property. In organic solvents, such as common ethanol, acetone, etc., because the polar groups contained in the molecular structure interact with the organic solvent molecules, they have a certain solubility. However, in water, because the overall molecular polarity is not extremely strong, and some structures are hydrophobic, the solubility in water is weak.
In addition, its density also has a specific value, which is related to the molecular mass and the way of molecular accumulation. This density characteristic is of great significance in operations such as separation and mixing.
Its appearance is mostly white or white powder, which is convenient for storage, transportation and subsequent chemical operation. The above physical properties are indispensable for the study of the chemical behavior, synthesis methods and practical applications of this compound.

2 - [ (6 -cyano- 2 -methyl-4 -pyridyl) amino] - 5 -nitrobenzenesulfonic acid is an organic compound. This compound has multiple chemical properties:
One is acidic. Due to its structure containing sulfonic acid groups (-SO-H), hydrogen ions can be ionized in water, showing acidity, and can neutralize with bases to generate corresponding sulfonates and water. For example, reaction with sodium hydroxide: 2 - [ (6-cyanogen-2-methyl-4-pyridyl) amino] - 5-nitrobenzenesulfonic acid + NaOH → 2 - [ (6-cyanogen-2-methyl-4-pyridyl) amino] - 5 -nitrobenzenesulfonic acid + H2O O.
The second is nucleophilic substitution reactivity. The (6-cyanogen-2-methyl-4-pyridyl) part of the compound is connected to the nitrogen atom. The nitrogen atom has lone pair electrons and has certain nucleophilic properties. It can undergo nucleophilic substitution reactions with electrophilic reagents under suitable conditions. For example, in the reaction with the halogenated hydrocarbon R-X, the lone pair electron of the nitrogen atom attacks the carbon atom connected to the halogen in the halogenated hydrocarbon, and the halogen atom leaves as a leaving group to form a new C-N bond compound: 2 - [ (6 - cyano- 2 - methyl - 4 - pyridyl) amino] - 5 - nitrobenzenesulfonic acid + R - X → 2 - [ (6 - cyano- 2 - methyl - 4 - pyridyl) - N - R - amino] - 5 - nitrobenzenesulfonic acid + HX < Br > The third is the property of nitro group. The compound contains nitro (-NO 2O), and the nitro group is a strong electron-absorbing group, which reduces the electron cloud density of the benzene ring and makes the electrophilic substitution reaction on the benzene ring difficult. However, under certain conditions, the nitro group can undergo a reduction reaction. For example, under the action of metals (such as iron, zinc, etc.) and acids (such as hydrochloric acid), the nitro group can be gradually reduced to an amino group (-NH2O), generating new compounds containing amino groups, providing diverse possibilities for subsequent organic synthesis.
The fourth is the reactivity of cyanyl groups. Cyanyl groups (-CN) can undergo various reactions, such as hydrolysis under acidic or alkaline conditions, to form carboxyl groups (-COOH) or amide groups (-CONH2O). In acidic hydrolysis, 2 - [ (6 - cyano- 2 - methyl - 4 - pyridyl) amino] - 5 - nitrobenzenesulfonic acid reacts with water, and finally forms carboxylic acid through the intermediate amide: 2 - [ (6 - cyano- 2 - methyl - 4 - pyridyl) amino] - 5 - nitrobenzenesulfonic acid + 2H ² O + H < unk > → 2 - [ (6 - carboxyl - 2 - methyl - 4 - pyridyl) amino] - 5 - nitrobenzenesulfonic acid + NH.

To prepare 2- [ (6-cyano- 2-methyl-4-pyrimidinyl) amino] -5-chloronicotinamide acid, the following ancient method can be followed:
First, the common raw materials are obtained through multiple delicate reactions. First, take a suitable starting material and put it in a specific reaction environment, or heat it, or catalyze it to change the intermolecular bonding. For example, the compound containing cyanogroup, methyl group and pyrimidinyl group is used as the group, and the amino group is introduced through the reaction of amination. This process requires controlling the temperature, duration and dosage of reagents. It is difficult to achieve expectations if there is a slight difference. < Br > When amination, select the appropriate amination reagent and add it according to the exact ratio. The reaction environment may be a liquid phase, and the reactants are dissolved in a suitable solvent to increase the chance of molecular collision and promote the smooth reaction. After the reaction is completed, the impurities are removed by the method of separation and purification to obtain a pure intermediate product.
Then, the intermediate product is chlorinated and chlorine atoms are introduced. The method of chlorination is to use chlorine gas or a specific chlorination reagent to precisely replace the group at the desired position under controlled conditions. This step also focuses on the control of conditions to prevent excessive chlorination or chlorination position deviation.
Chlorination is completed, and then through a series of transformations, the molecular structure is gradually close to the target product. Or through hydrolysis, condensation and other reactions to construct the structural part of nicotinamide acid. Each step of the reaction requires careful observation of the reaction process and monitoring by appropriate means, such as thin-layer chromatography, to know whether the reaction is complete and whether the product is pure.
After each step of the reaction is completed, after multiple separation and purification operations, such as recrystallization, column chromatography, etc., high-purity 2- [ (6-cyano2-methyl-4-pyrimidinyl) amino] -5-chloronicotinamide acid is obtained. This whole process requires the experimenter to have exquisite skills and a rigorous attitude, so that the synthesis can be smooth and satisfactory results can be obtained.
