The method of preparing α-methylpyridine-2-methanol often follows the following methods.
First, the key intermediate is obtained by lithium reaction with 2-methylpyridine as the starting material. First take an appropriate amount of anhydrous ether, put it in a clean reactor, fill it with nitrogen to drive out the air, and create an oxygen-free atmosphere. Slowly drop 2-methylpyridine into the ether solution containing butyllithium, and stir the reaction at a low temperature, such as -78 ° C. The lithium atom of butyllithium is replaced with the methyl active hydrogen of 2-methylpyridine to form a lithiated intermediate. Then, carefully add paraformaldehyde, heat it up to a moderate level, such as about 0 ° C, and continue to stir. Lithium intermediates react with paraformaldehyde to form alkoxides. Finally, dilute acids, such as dilute hydrochloric acid, are carefully acidified to convert the alkoxides into α-methylpyridine-2-methanol, and then purified by extraction and distillation.
Second, start with 2-cyanopyridine. Put 2-cyanopyridine and a suitable solvent, such as ethanol, into a reaction vessel, add a catalyst such as Raney Nickel, pass hydrogen, and catalyze hydrogenation at a certain pressure, such as 1-3 MPa, and temperature, such as 50-80 ° C. The cyano group is gradually reduced to hydroxymethyl groups to produce α-methylpyridine-2-methanol. After the reaction is completed, the catalyst is filtered off and the reaction solution is distilled to obtain a relatively pure product.
Third, 2-pyridine formaldehyde is used as the raw material. In a reactor, 2-pyridine formaldehyde is reacted with an appropriate amount of methylhalide magnesium, such as methylbromide, in anhydrous ether or tetrahydrofuran solvent at low temperature. The methyl group of Grignard's reagent is nucleophilically added to the aldehyde group of 2-pyridine formaldehyde to form a magnesium salt. The quenching reaction is added with water, neutralized by acid, extracted and separated, distilled and purified, and alpha-methylpyridine-2-methanol is also obtained.
These various production methods have their own advantages and disadvantages, and they need to be carefully selected according to the actual situation, such as raw material availability, cost, product purity requirements, etc.

Alpha-Methylpyridine-2-methanol, that is, α-methylpyridine-2-methanol, this material should be paid attention to during storage and transportation.
It is flammable, and it is easy to burn in case of open flames and hot topics. Therefore, when storing, it should be placed in a cool and ventilated warehouse, away from fire and heat sources, and the storage temperature should not exceed 30 ° C. The warehouse should have suitable materials to contain leaks. Be sure to pack and unload lightly during handling to prevent damage to packaging and containers.
Furthermore, alpha-Methylpyridine-2-methanol is toxic and can pose a hazard to human health. The storage place should be stored separately from oxidants, acids and alkalis, and should not be mixed to avoid dangerous chemical reactions. When transporting, it is necessary to ensure that the container does not leak, collapse, fall or damage. Transportation vehicles should be equipped with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment. In summer, it is advisable to transport in the morning and evening to prevent sunlight exposure. Highway transportation should follow the specified route, and do not stop in residential areas and densely populated areas.
In addition, it may be harmful to the environment and cannot be discharged at will. In the event of a leak, personnel from the leaked contaminated area should be quickly evacuated to a safe area and isolated, and access should be strictly restricted. Emergency personnel need to wear self-contained positive pressure breathing apparatus and anti-toxic clothing to cut off the source of leakage as much as possible to prevent it from flowing into restricted spaces such as sewers and flood drains.
Only in this way can we ensure safety and avoid accidents during the storage and transportation of alpha-Methylpyridine-2-methanol.
