The synthesis method of 2-thiophene methylamine has been used in ancient times, and there are many methods, each of which is exquisite. The following is a detailed description of Jun.
First, thiophene is used as the starting material with formaldehyde and hydroxylamine hydrochloride. First, thiophene and formaldehyde are reacted under specific conditions to generate the corresponding intermediate. In this step, attention should be paid to the control of the reaction temperature and time. If the temperature is too high or the time is too long, it is easy to cause side reactions. Then the intermediate is further reacted with hydroxylamine hydrochloride, and after many transformations, 2-thiophene methylamine can be obtained. The raw materials of this method are relatively common, but the reaction steps are slightly complicated and the reaction conditions are strict.
Second, 2-bromomethylthiophene is used as the starting material. Make it undergo nucleophilic substitution reaction with ammonia or amine compounds. In this reaction process, the choice of ammonia or amine compounds is crucial, and different amines have different reactivity and selectivity. Appropriate solvents and bases need to be selected during the reaction to promote the reaction and improve the yield of the product. This method is relatively simple, but the preparation of 2-bromomethylthiophene may require additional steps.
Third, thiophene-2-formaldehyde is used as the raw material. First, thiophene-2-formaldehyde is reduced to thiophene-2-methanol. Suitable reducing agents, such as sodium borohydride, can be selected for this reduction process. The conditions are mild and the operation is convenient. Then thiophene-2-methanol is reacted with a halogenating agent to convert into a halogen, and then reacted with ammonia to obtain 2-thiophene methylamine by nucleophilic substitution. The reaction steps of this path are relatively mature, but attention needs to be paid to the separation and purification after each step to ensure the purity of the product.
The above synthesis methods have their own advantages and disadvantages. In practical applications, it is necessary to comprehensively consider the availability of raw materials, cost, product purity and many other factors, and make a careful choice to achieve the ideal synthesis effect.
