To prepare N-ethyl-4-pyridylmethylamine, the following methods can be used.
First, 4-pyridyl formaldehyde and ethylamine are used as raw materials and prepared by reductive amination reaction. First, 4-pyridyl formaldehyde and ethylamine are mixed in a suitable organic solvent, such as methanol or ethanol, in an appropriate proportion, and an appropriate amount of acid catalyst, such as acetic acid, is added to promote the condensation of the two to form an imine intermediate. Subsequently, a reducing agent, such as sodium borohydride or sodium cyanoborohydride, is added to reduce the imine to the target product N-ethyl-4-pyridylmethylamine under mild conditions. In this process, the solvent needs to be kept dry, and the reaction temperature should be properly controlled, generally between 0 ° C and room temperature, to ensure that the reaction proceeds smoothly and there are few side reactions.
Second, 4-chloromethylpyridine hydrochloride is prepared by reacting with ethylamine. Dissolve 4-chloromethylpyridine hydrochloride in a suitable solvent, such as dichloromethane or toluene, and add ethylamine dropwise in the presence of a base. The base can be triethylamine or potassium carbonate, etc. Its function is to neutralize the hydrogen chloride generated by the reaction, so that the reaction equilibrium moves in the direction of the product. After the reaction is completed, pure N-ethyl-4-pyridylmethylamine can be obtained through extraction, washing, drying and vacuum distillation.
Third, using 4-methylpyridine as the starting material, the radical substitution reaction occurs with N-chlorosuccinimide (NCS) in the presence of an initiator, and chlorine atoms are introduced into the 4-position methyl of pyridine to obtain 4-chloromethylpyridine. Then it is reacted with ethylamine in a similar manner as described above to obtain N-ethyl-4-pyridylmethylamine. This route has a little more steps, but the raw material 4-methylpyridine is relatively easy to obtain, and a higher yield can be achieved by reasonably controlling the reaction conditions of each step.
The above methods have their own advantages and disadvantages. In actual preparation, it is necessary to comprehensively consider the raw material cost, reaction conditions, equipment requirements and product purity and other factors to choose the most suitable method.

N - Ethyl - 4 - pyridinemethanamine is an organic compound. When using it, many things need to be paid attention to.
First safety protection. This compound may be toxic and irritating, and protective equipment must be complete during operation. For example, wear appropriate protective gloves to prevent it from coming into contact with the skin, causing skin damage, allergies, etc.; equipped with protective glasses, which can protect against eye damage. If it is not careful, it may cause pain, redness and even visual damage. Wearing protective clothing is also indispensable, which can reduce its potential harm to the body in all aspects.
Second words operating environment. It should be operated in a well-ventilated place, which can promote the discharge of volatile compound gases as soon as possible, avoid accumulation in a limited space, and reduce the risk of poisoning. If conditions permit, it is more appropriate to operate in a fume hood, which can effectively isolate harmful gases and ensure the safety of operators.
Furthermore, caution is also required when storing. It should be stored in a cool, dry place, away from fire sources and oxidants. Because of its flammability, it is easy to cause combustion and explosion accidents in case of open flames and hot topics; contact with oxidants may also cause violent reactions, endangering safety. Storage containers must be well sealed to prevent leakage and clearly marked to avoid misuse.
In addition, accurate measurement is essential during use. According to the experimental or production requirements, accurately measure the required amount to avoid waste and ensure the accuracy of the reaction or production process. After the operation is completed, the remaining compounds and used appliances must be properly disposed of. It should not be discarded at will, and should be recycled or treated harmlessly in accordance with relevant regulations to avoid pollution to the environment.
