To prepare 2-pyridylmethylamine and 4-methoxy, there are many methods, and it is as common as Chen.
First, 4-methoxy-2-pyridylcarboxylic acid is used as the starting material. First, the acid is carefully reduced in a low temperature and inert gas protected environment with an appropriate reducing agent, such as lithium aluminum hydride. The amount of lithium aluminum hydride, the reaction temperature and time need to be precisely controlled. In this process, the carboxyl group of the acid is reduced to an alcoholic hydroxyl group to obtain 4-methoxy-2-pyridylmethanol. Then, with a suitable halogenating agent, such as thionyl chloride, the alcohol hydroxyl group is converted into a halogen atom to generate 4-methoxy-2-pyridyl halomethane. Finally, ammonia or amine reagents are used to react with it, and the halogen atom is replaced by an amino group. Then the target product is 2-pyridylmethylamine and 4-methoxy.
Second, 4-methoxy-2-pyridyl formaldehyde is used as the raw material. First, formaldehyde is reacted with ammonia and a suitable reducing agent, such as sodium cyanoborohydride, in a buffer solution system. This reaction requires attention to control the pH value, temperature and reaction time of the solution. Under mild conditions, sodium cyanoborohydride can promote the reductive amination of aldehyde groups with ammonia to directly generate 2-pyridylmethylamine and 4-methoxy groups. After the reaction, the pure product can be obtained by extraction, column chromatography and other separation and purification methods.
Third, starting from the pyridine derivatives containing suitable substituents, the amino groups are constructed through multi-step reactions. For example, starting with 4-methoxy-2-halopyridine, first react with metal-organic reagents, such as Grignard reagent, introduce appropriate carbon chain fragments, and then transform the functional groups, such as converting the introduced functional groups into active groups that can react with ammonia, and finally reacting with ammonia to introduce amino groups, and then obtain the target product after subsequent treatment. There are many steps in this route, but if the reaction conditions of each step are properly optimized, the product with higher yield can also be obtained.

2-Pyridylmethylamine, 4-methoxy When using this substance, many matters need to be paid attention to.
First, safety first. This substance may be toxic and irritating. When operating, it is necessary to wear suitable protective equipment, such as gloves, goggles and protective clothing, to prevent it from contacting the skin, eyes and respiratory tract. In case of inadvertent contact, rinse with plenty of water as soon as possible. In severe cases, seek medical attention immediately.
Second, storage should also be paid attention to. It should be placed in a cool, dry and well-ventilated place, away from fire, heat and oxidants. Due to its chemical activity, improper storage or danger.
Third, accurate access. In view of its crucial role in the reaction, when taking it, it is necessary to measure it with accurate gauges, according to the amount required by the experiment or production. It must not be increased or decreased at will, so as not to affect the results or product quality.
Fourth, understand the reaction characteristics. When participating in a chemical reaction, it is necessary to clarify its reaction mechanism, conditions and possible side reactions. This helps to optimize the reaction process and improve yield and purity.
Fifth, follow regulations. The use process must strictly abide by relevant regulations and standards. Whether it is emission disposal or experimental records, it should not be sloppy to ensure environmental safety and human health. Remember to operate with caution to ensure safety and achieve the expected effect.
