The synthesis method of 3-chloro-4-pyridyl methylamine is not directly described in the ancient book Tiangong Kaiwu, but it can be deduced according to the ancient chemical technology and similar synthesis ideas.
One, or follow the method of substitution reaction. Using pyridine as the base, chlorine atoms are introduced before the third position of the pyridine ring. Although ancient chemistry does not have today's precise instruments, under suitable reaction conditions, chlorine-containing reagents, such as chlorine elementals, under the action of light or specific catalysts, pyridine can be substituted to obtain chloropyridine at the third position.
Then, methylamino groups are introduced at the fourth position. 3-Chloropyridine can be suitably modified first, such as halogenating it, to obtain a more active halogenated intermediate. Then, in an alkaline environment, a nucleophilic substitution reaction occurs with methylamine analogs, so that methylamino groups replace halogen atoms to obtain 3-chloro-4-pyridylmethylamine.
Second, or you can try to construct a pyridine ring strategy. Using simple compounds containing chlorine and amino groups as starting materials, pyridine rings are constructed through multi-step reactions. For example, chlorine-containing enamines and carbonyl-containing compounds are cyclized to form pyridine rings under the catalysis of acids or bases. After proper functional group transformation, the methylamino group is introduced at the 4th position, and the chlorine atom is retained at the 3rd position, and the final product is obtained.
Although the ancient techniques are very different from the present, the basic principles of chemistry are the same. This idea can simulate the ancient synthesis of 3-chloro-4-pyridylmethylamine.

3-Chloro-4-pyridylmethylamine is also a chemical substance. When storing and transporting, pay attention to many matters.
First storage. This substance should be placed in a cool, dry and well-ventilated place. If it is exposed to high temperature and humidity, or its properties may change, it may even cause chemical reactions. For example, high temperature can accelerate the decomposition of some chemicals, and humid environment may promote reactions such as hydrolysis, so it is necessary to ensure that the storage environment is suitable. In addition, it must be stored separately from oxidants, acids, bases and other substances. This is due to the chemical properties of 3-chloro-4-pyridylmethylamine, or violent reactions with the above substances, such as oxidation-reduction reactions, acid-base neutralization reactions, etc., which can cause hazards such as fire and explosion. And the storage place should be equipped with suitable materials to contain leaks, in case of leakage, it can be dealt with in time to prevent its spread from causing greater harm.
As for transportation, it should not be ignored. The transportation vehicle must ensure that the vehicle is in good condition and has corresponding safety facilities. During transportation, it should be protected from exposure to the sun, rain, and high temperature. If exposed to the hot sun or rain, it may affect its stability. At high temperatures, the activity of chemicals increases, making it easier to cause dangerous reactions. The escort personnel should also be familiar with its nature and emergency handling methods. If there is an unexpected situation on the way, such as leakage, etc., they can respond in time and take correct measures, such as evacuating the crowd, blocking the scene, and properly handling the leakage. When loading and unloading, the operation needs to be light and light, and it is strictly forbidden to drop and heavy pressure. If the packaging is damaged, or the material leaks, and the improper loading and unloading force or triggers internal chemical reactions, it endangers safety.
In short, during the storage and transportation of 3-chloro-4-pyridylmethylamine, it is necessary to exercise caution and operate in strict accordance with relevant specifications to ensure the safety of personnel and the environment.
