To prepare 2-chloromethyl-3-methyl-4- (2,2,2-trifluoroethoxy) pyridine hydrochloride, the following ancient method can be used.
First, 3-methyl-4-hydroxypyridine is used as the starting material, which is the root of the reaction. Place it in an appropriate reactor and add an appropriate amount of aprotic polar solvent, such as N, N-dimethylformamide (DMF), which can fully disperse the reactants and facilitate the reaction. Subsequently, alkali substances, such as potassium carbonate, are added, which can activate hydroxyl groups and increase the reactivity. Mix well to maintain the system at a certain temperature, such as 50-60 ° C. This temperature range not only guarantees the reaction rate, but also avoids excessive side reactions.
Next, slowly add 2,2,2-trifluoroethyl halide dropwise, such as 2,2,2-trifluoroethyl bromide. This halide undergoes nucleophilic substitution with the activated hydroxyl group to form 3-methyl-4- (2,2,2-trifluoroethoxy) pyridine. This step requires continuous stirring to make the reactants fully contacted and the reaction is complete. After the reaction is completed, the product is extracted with a suitable organic solvent, such as dichloromethane, dried with anhydrous sodium sulfate, and the solvent is removed by rotary evaporation to obtain 3-methyl-4- (2,2,2-trifluoroethoxy) pyridine crude product. Purified by column chromatography to obtain a purified product.
Then, the purified 3-methyl-4- (2,2,2-trifluoroethoxy) pyridine is placed in another reaction vessel, and an appropriate amount of dichloromethane is added as a solvent. In a low temperature environment, such as 0-5 ° C, hydrogen chloride gas is slowly introduced, and strong stirring is carried out at the same time. During this process, the nitrogen atom of the pyridine ring combines with hydrogen chloride to form a pyridine hydrochloride. And under this low temperature condition, a chloromethylating agent, such as chloromethyl ether, is added to the system to undergo a chloromethylation reaction, and chloromethyl is introduced into the 2-position of the pyridine ring to obtain 2-chloromethyl-3-methyl-4- (2,2,2-trifluoroethoxy) pyridine hydrochloride. After the reaction is completed, the solvent is removed under reduced pressure, and then recrystallized with a suitable organic solvent to improve the purity of the product.

2-Chloromethyl-3-methyl-4- (2,2,2-trifluoroethoxy) pyridine hydrochloride, this is a fine chemical, and many matters need to be paid attention to during storage and transportation.
First of all, storage, this substance should be stored in a cool, dry and well ventilated place. Because of its nature or affected by temperature and humidity, if it is in a high temperature environment, it may cause decomposition and deterioration; when the humidity is high, it may absorb water vapor, which affects its purity and stability. And it needs to be kept away from fire and heat sources. Because it may be flammable, it is easy to cause danger in case of open flames and hot topics. Furthermore, it should be stored separately from oxidizing agents, acids, alkalis, etc., due to contact with them or chemical reactions, resulting in safety accidents. The storage area should also be equipped with suitable materials to contain leaks in case of leakage, which can be dealt with in time.
As for transportation, it must be lightly loaded and unloaded when handling, and must not be brutally loaded and unloaded to avoid packaging damage. During transportation, 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. It is best to transport in the morning and evening in summer to avoid high temperature periods to prevent excessive temperature from affecting the properties of substances. During transportation, it should be protected from exposure to the sun, rain, and high temperature. Road transportation should follow the prescribed route, do not stop in residential areas and densely populated areas. It is forbidden to slip during railway transportation.
In this way, careful treatment of storage and transportation can ensure the safety of 2-chloromethyl-3-methyl-4- (2,2,2-trifluoroethoxy) pyridine hydrochloride, avoid accidents, and ensure the safety of people and the environment.
