The synthesis of 1 - (4 -aminophenyl) pyridine is an interesting topic in organic synthetic chemistry. Although the synthesis method is not directly described in Tiangong Kaiwu, we can explore possible ways based on the basic principles of chemical synthesis and the chemical ideas contained in ancient books.
First, the skeleton of this compound can be constructed by nucleophilic substitution reaction. Using suitable halogenated pyridine and aminobenzene derivatives as raw materials, nucleophilic substitution is carried out under the action of suitable bases and catalysts. For example, a halogenated pyridine with high halogen atom activity, such as bromopyridine or iodopyridine, is mixed with p-aminobenzene derivatives in an organic solvent, potassium carbonate, sodium carbonate and other bases are added to neutralize the halogenated hydrogen, and then copper salts, palladium salts and other catalysts are added to improve the reaction activity and selectivity. Stirring the reaction at an appropriate temperature is expected to obtain the target product.
Second, the coupling reaction catalyzed by transition metals is also a feasible method. Pyridine boric acid derivatives and halogenated aminobenzene are used as starting materials, and carbon-carbon bonds are formed under basic conditions in the presence of transition metal catalysts such as palladium catalysts according to the Suzuki coupling reaction mechanism. This method requires fine regulation of the reaction conditions, such as selecting suitable ligands to enhance the activity and selectivity of the catalyst, controlling the type and dosage of bases, optimizing the reaction temperature and time, in order to achieve the purpose of efficient synthesis.
Third, the gradual construction of molecular structure can also be considered. First modify the pyridine ring or benzene ring, introduce a specific functional group, and then transform the functional group and ligation reaction to finally achieve the synthesis of 1- (4-aminophenyl) pyridine. For example, the pyridine is nitrified first, then the nitro is reduced to an amino group, and then the amino benzene is partially connected to it through an appropriate reaction. This process requires precise control of the reaction conditions at each step to ensure the selectivity and yield of the reaction.
The above methods are only theoretical speculations. In practice, the reaction needs to be optimized and adjusted according to the specific experimental conditions and raw material characteristics, so as to achieve the effective synthesis of 1- (4-aminophenyl) pyridine.

1- (4-aminophenyl) pyridine is an organic compound, which has the following physical and chemical properties:
In terms of appearance properties, it is mostly solid at room temperature, and the color may be white to light yellow powder. This appearance characteristic helps to distinguish this substance. In actual operation and observation, this characteristic can be used as a preliminary basis for judgment.
Melting point is one of the key physical properties of substances. 1- (4-aminophenyl) pyridine has a specific melting point. Its purity can be preliminarily evaluated by measuring the melting point. The melting point range of high-purity substances is relatively narrow.
In terms of solubility, it has a certain solubility in some organic solvents such as ethanol and dichloromethane, but it has a low solubility in water. This difference in solubility makes it possible to select suitable solvents according to their characteristics when separating, purifying and reacting the substance. For example, in some organic synthesis reactions, if the substance needs to be fully dissolved to promote the reaction, an organic solvent with better solubility such as ethanol can be selected as the reaction medium.
In terms of chemical properties, amino groups and pyridine rings give the substance significant chemical activity. Amino groups are basic and can react with acids to form salts. In the field of organic synthesis, this property can be used to prepare salts with specific structures, thereby improving the solubility and stability of substances. Pyridine rings are rich in electrons and are prone to electrophilic substitution reactions, such as halogenation, nitrification, and sulfonation. These reactions can introduce various functional groups on the pyridine ring, which greatly expands the application range of the substance in organic synthesis, and can be used to construct more complex organic molecular structures. It has important value in many fields such as drug synthesis and material preparation.

In today's world, in the market, it is difficult to determine the price of (1- (4-aminopyridine)) blown medicine. The change in its price depends on multiple ends, and it cannot be hidden in one word.
The first is the raw material made by it, which is of great concern to the price. The abundance of raw materials, the difficulty of obtaining them, all make the price different. If the raw materials are rich and easy to obtain, the price will be flat; if the raw materials are thin and difficult to harvest, the price will be high.
Second, the production method is also clumsy. If there is an exquisite method that can reduce its consumption and increase its production, the price can be lowered; if the method is clumsy, it will take a long time, consume a lot of money, and the price will be high.
In addition, the demand of the city is also a major factor. If there are many people in need, the supply will exceed the demand, and the price will rise; if there are few people in need, if the supply exceeds the demand, the price will be depressed.
Moreover, the place where you are located is different, and the tax system is different, which also makes the price different. Or because of the remote location, the inconvenience of transportation, the cost will increase greatly, and the price will also go up.
In summary, if you want to know the price of (1 - (4 - aminopyridine)) blowing medicine in the market, when you consider the situation of raw materials, the method of production, the needs of the market, taxes and transportation, you can't just judge it with one end. Its price is constantly changing, high and low, and only by carefully observing all things can we obtain a more certain price.
