4-bromo-3-fluorobenzyl amine.. what is the synthesis method of HCl
The synthesis of 4-bromo-3-fluorobenzyl amine hydrochloride can follow the following steps.
First, 4-bromo-3-fluorobenzoic acid is used as the starting material. First, it is co-placed with dichlorosulfoxide in a suitable reaction vessel and reacted at an appropriate temperature. This step aims to convert the carboxyl group into an acyl chloride, which is a commonly used acyl chloride reagent. It reacts with carboxylic acid to generate an acid chloride efficiently, while escaping sulfur dioxide and hydrogen chloride gas. After the reaction, the excess dichlorosulfoxide is removed by means of reduced pressure distillation to obtain 4-bromo-3-fluorobenzoyl chloride.
Next, dissolve the prepared 4-bromo-3-fluorobenzoyl chloride in an appropriate amount of organic solvent, such as dichloromethane. Under low temperature and stirring conditions, slowly add a solution containing excess ammonia water dropwise. This acid chloride reacts with ammonia water to form 4-bromo-3-fluorobenzamide. This step requires attention to temperature control to prevent side reactions. After the reaction is completed, 4-bromo-3-fluorobenzamide is separated by extraction, washing, drying, etc.
Furthermore, 4-bromo-3-fluorobenzamide is reacted with lithium aluminum hydride in an anhydrous organic solvent such as anhydrous tetrahydrofuran. Lithium aluminum hydride is a strong reducing agent, and the carbonyl group of the amide can be reduced to methylene to obtain 4-bromo-3-fluorobenzyl amine. After the reaction, the product is carefully treated, such as quenching excess lithium aluminum hydride with an appropriate amount of water, and then purified by extraction, drying, column chromatography and other steps. At the end of
, the obtained 4-bromo-3-fluorobenzyl amine is dissolved in an organic solvent, and dry hydrogen chloride gas is introduced to obtain 4-bromo-3-fluorobenzyl amine hydrochloride. This step is a salt-forming reaction, hydrogen chloride and benzyl amine form a salt, making the product more stable and easy to store and subsequent treatment. After suction filtration and drying, pure 4-bromo-3-fluorobenzyl amine hydrochloride can be obtained.
4-bromo-3-fluorobenzyl amine.. HCl during storage and transportation
4-Bromo-3-fluorobenzyl amine hydrochloride, this is a chemical substance, and there are several important things to pay attention to when storing and transporting.
First of all, storage should be placed in a cool and dry place because of its nature. Because shade can slow down the speed of chemical changes, drying can avoid moisture hydrolysis and other conditions. If it is in a humid environment, water may react with some components in 4-bromo-3-fluorobenzyl amine hydrochloride, causing it to deteriorate. And the storage must be well ventilated to avoid the accumulation of harmful gases and keep the environment safe. In addition, keep away from fire and heat sources. This compound may be flammable, and in case of fire or heat, there is a risk of combustion or even explosion.
As for transportation, it should not be neglected. It is necessary to ensure that the packaging is intact to prevent its leakage. The materials used in packaging, when chemically resistant, can withstand collisions and vibrations during transportation. When transporting, they should be separated from oxidants and acids, etc., because they may react violently with them, endangering transportation safety. Transportation vehicles should also be equipped with corresponding fire equipment and leakage emergency treatment equipment. If there is a sudden, they can be responded to in time. During driving, drivers should be steady to avoid sudden brakes and sharp turns to reduce the possibility of damage to items. Therefore, Fangbao 4-bromo-3-fluorobenzamine hydrochloride is safe during storage and transportation.
