There are various ways to synthesize Methyl 2- (aminomethyl) pyridine-4-carboxylate hydrochloride. One is to use methyl 2-cyanopyridine-4-carboxylate as the starting material, and first reduce the cyanyl group to aminomethyl group. This reduction process can be achieved by catalytic hydrogenation, using palladium carbon as a catalyst, at a suitable hydrogen pressure and temperature, to obtain hydrogen from cyanyl group and turn it into aminomethyl group. However, catalytic hydrogenation requires specific equipment, and the reaction conditions are also strictly controlled.
Furthermore, chemical reduction methods can be adopted, such as a system composed of sodium borohydride and nickel chloride, which can also reduce cyanyl group to aminomethyl group. This system is relatively mild, does not require special high-pressure equipment, and is slightly easier to operate. After obtaining 2- (aminomethyl) pyridine-4-carboxylate, it reacts with hydrogen chloride to form its hydrochloride. The 2- (aminomethyl) pyridine-4-carboxylate can be dissolved into a suitable organic solvent, such as ether or dichloromethane, and hydrogen chloride gas is introduced to obtain the target product Methyl 2- (aminomethyl) pyridine-4-carboxylate hydrochloride.
Another route is to use 2-halogenated methyl pyridine-4-carboxylate as the starting material and react with aminomethylation reagents. Commonly used aminomethylation reagents, such as ulotropine, react with it first, and then hydrolyze to obtain 2- (aminomethyl) pyridine-4-carboxylate, and then form hydrochloride according to the previous method. This approach is easier to obtain raw materials, but the reaction steps are slightly more, and the reaction conditions of each step need to be carefully controlled to preserve yield and purity.

Methyl-2- (aminomethyl) pyridine-4-carboxylic acid hydrochloride This product requires careful attention during storage and transportation.
When storing, the temperature and humidity of the environment should be the first priority. It should be stored in a cool and dry place. If the temperature and humidity of the environment are too high, it may cause deliquescence and deterioration. Because hydrochloride is prone to moisture absorption, once it is damp, it will not only affect its purity, but also cause chemical reactions and damage its quality.
Furthermore, it should be stored away from fire and heat sources. This compound may be flammable to a certain extent, close to the source of fire and heat, and may cause fire and explosion, endangering safety. And it needs to be placed separately from oxidizing agents, acids, alkalis and other chemicals. Because of its active chemical properties, contact with the above substances is prone to violent reactions, causing changes in ingredients and increasing safety hazards.
During transportation, the packaging must be tight. Appropriate packaging materials should be selected to ensure that the transportation is not damaged or leaked. If leakage occurs, it will not only cause material loss, but also disperse and escape, or be harmful to the transportation environment and personnel health. Transportation vehicles should also be equipped with corresponding fire protection and leakage emergency treatment equipment to prevent accidents. Escort personnel should be familiar with the nature of this object and emergency treatment methods. Transportation routes should avoid densely populated areas and traffic arteries to reduce the risk of accidents and ensure transportation safety.
