The synthesis method of 5-methyl-2-pyridinomethanol has been known in ancient times, and is described in this article.
First, 5-methyl-2-pyridinecarboxylic acid is used as the starting material. This is a common method. First, 5-methyl-2-pyridinecarboxylic acid is reacted with a strong reducing agent, such as lithium aluminum hydride, in a suitable organic solvent, such as anhydrous tetrahydrofuran, under low temperature and strict anhydrous and anaerobic conditions. Lithium aluminum hydride is highly reducing, and carboxyl groups can be reduced to hydroxymethyl groups to obtain 5-methyl-2-pyridinecarboxylic alcohol. After the reaction is completed, the reaction system needs to be carefully handled. The excess aluminum hydride lithium is carefully hydrolyzed with dilute acid, and then the product is purified through extraction, washing, drying, distillation and other steps.
Second, starting from 5-methyl-2-halopyridine. Halopyridine has high activity and can react with metal magnesium to make Grignard reagent. 5-methyl-2-halopyridine and magnesium chips are placed in anhydrous ether to initiate a reaction to obtain Grignard reagent. Then, the ether solution of formaldehyde is slowly added to the Grignard reagent. The Grignard reagent undergoes a nucleophilic addition reaction with formaldehyde. After hydrolysis, 5-methyl-2-pyridine methanol can also be obtained. Subsequent operations also need to go through a series of separation and purification operations to obtain a purified product.
Third, 5-methylpyridine is used as a raw material. 5-methylpyridine can be halogenated by side chain first. For example, N-bromosuccinimide (NBS) is used in the presence of an initiator to replace the hydrogen on the methyl group of the side chain of the pyridine with a bromine atom to generate 5-methyl-2-bromomethylpyridine. This bromomethylpyridine is then reacted with nucleophiles, such as methanol solution of sodium methoxide, the bromine atom is replaced by methoxy group, and then hydrolyzed to convert into 5-methyl-2-pyridine methanol. Finally, the product is further purified by recrystallization, column chromatography and other methods.
These are all methods for synthesizing 5-methyl-2-pyridine methanol, each has its own advantages and disadvantages, and needs to be selected according to the actual situation.

5-Methyl-2-pyridyl methanol is an organic compound. During storage and transportation, the following things should be paid attention to:
First, when storing, it should be placed in a cool, dry and well-ventilated place. This is because it has certain chemical activity, high temperature, humid environment or cause it to deteriorate. If it is in a high temperature, it may cause a chemical reaction and change its chemical structure; in a humid environment, or absorb moisture, which affects the purity.
Second, it must be stored separately from oxidizing agents, acids and other substances. The chemical properties of 5-methyl-2-pyridyl methanol determine that it comes into contact with oxidants or reacts violently, and even causes dangers such as combustion and explosion; coexists with acid substances, or reacts with acid and base, causing it to fail or form dangerous products.
Third, choose the appropriate material for the storage container. In general, corrosion-resistant containers, such as glass or specific plastic materials, should be used. Because of its reaction with certain metal materials, the container will corrode and also affect the purity of the substance.
Fourth, during transportation, it is necessary to ensure that the container is well sealed. To prevent leakage, if it leaks into the environment, or causes pollution to the environment, and the substance may be harmful to the human body, once leaked, or endanger the health of the transporter and surrounding people.
Fifth, relevant regulations and standards must be followed when transporting such chemical substances. Professional qualifications and licenses are required for transporting such chemical substances, and professional training is also required for transporters to be familiar with their hazards and emergency treatment methods, so as to ensure transportation safety and avoid accidents.
