To prepare 2- (naphthalene-1-ylmethyl) -4,5-dihydro-1H-imidazole hydrochloride (1:1), there are many methods, and the selection is mainly described.
First, naphthalene formaldehyde and ethylenediamine can be used as the starting point, and naphthalene formaldehyde and ethylenediamine can be condensed to obtain the intermediate Schiff base. In this step, the reaction temperature, time and material ratio need to be controlled. The temperature may be between 50 and 80 ° C. When the number of reactions, the material should be 1:1.2 - 1.5 to promote the efficient generation of Schiff base. Then the Schiff base is reduced to hydrogen in the presence of a suitable catalyst such as Raney nickel, hydrogenation pressure or 2-5 MPa, temperature 40-60 ℃, so that the double bond is hydrogenated to form 2- (naphthalene-1-ylmethyl) -4,5-dihydro-1H-imidazole. The final acid is acidified with hydrochloric acid to obtain the target product. The acid dosage needs to be accurate to obtain a 1:1 hydrochloride.
Second, naphthalene methyl halide can also be used to react with imidazole derivatives. The first naphthalene methyl halide is prepared, such as the reaction of naphthalene and halomethane under the catalysis of Lewis acid, and the catalyst can be selected as aluminum trichloride, etc., at a low temperature of 0-10 ° C, and then the naphthalene methyl halide is prepared to react with 4,5-dihydro-1H-imidazole in the presence of a base, such as potassium carbonate, in an organic solvent such as acetonitrile, when the reflux number is heated, it can be formed into 2- (naphthalene-1-ylmethyl) -4,5-dihydro-1H-imidazole, followed by acidification with hydrochloric acid to obtain the target product.
Third, 1-naphthalene acetonitrile is used as the starting material, and it is first reduced to 1-naphthalene ethylamine. The reduction reagent can be selected from lithium aluminum hydride, etc., to control the reaction conditions. After 1-naphthalene ethylamine is reacted with formaldehyde and ammonium salts under suitable conditions, an imidazole ring can be constructed to form 2- (naphthalene-1-ylmethyl) -4,5-dihydro-1H-imidazole, and finally acidized with hydrochloric acid to obtain the required hydrochloride.
All synthesis methods have advantages and disadvantages, and the best path should be selected according to the actual conditions, raw material availability, cost and product purity requirements.

2-%28naphthalen-1-ylmethyl%29-4%2C5-dihydro-1H-imidazole + hydrochloride% 281% 3A1% 29 is 2- (naphthalene-1-ylmethyl) -4,5-dihydro-1H-imidazole hydrochloride (1:1). When storing and transporting this substance, many matters need to be paid attention to.
First, it is related to storage. This compound should be placed in a cool, dry and well-ventilated place. Because of the cool environment, it can reduce the risk of deterioration due to excessive temperature. If it is exposed to high temperature, or its chemical structure changes, it will lose its inherent characteristics. Drying is indispensable, because it is afraid of moisture, contact with water or cause reactions such as hydrolysis, which will damage the quality. Good ventilation can disperse harmful gases that may evaporate in time and maintain its stability. At the same time, it must be placed separately from oxidizing agents, acids, alkalis and other chemicals to prevent interaction and cause dangerous reactions.
Second, it involves transportation. During transportation, make sure that the packaging is intact. The packaging of this substance must be able to withstand a certain external force to avoid leakage due to package rupture. The transportation tool should also be clean, dry, and free of other chemicals to prevent cross-contamination. And the transportation process should avoid sun and rain, control the temperature and humidity of the transportation environment, and operate in strict accordance with the relevant regulations on chemical transportation to ensure transportation safety. In conclusion, when storing and transporting 2- (naphthalene-1-ylmethyl) -4,5-dihydro-1H-imidazole hydrochloride (1:1), care must be taken with regard to environmental conditions, packaging, and isolation from other substances to ensure its quality and safety.
