There are various methods for the synthesis of 1H-pyrrole-1-ethylamine. Today, the ancient method is described, which can help you solve your doubts.
First, it can be obtained from the reaction of 1- (2-bromoethyl) pyrrole with ammonia. First take an appropriate amount of 1- (2-bromoethyl) pyrrole and place it in a clean reaction vessel. This vessel needs to be able to withstand a certain pressure and temperature, and has good sealing. Then, slowly introduce ammonia gas. During the reaction, the temperature should be controlled in a moderate range, about 50 to 80 degrees Celsius. Due to the low temperature, the reaction rate is slow; if the temperature is too high, side reactions will easily occur. At the same time, it needs to be stirred continuously to make the reactants fully contact and promote the reaction. After several times of reaction, 1H-pyrrole-1-ethylamine crude product can be obtained. Subsequent separation and purification steps, such as distillation, extraction, etc., to obtain a pure product.
Second, pyrrole and 2-chloroethylamine hydrochloride are used as raw materials. First dissolve pyrrole in a suitable organic solvent, such as dichloromethane or N, N-dimethylformamide. The solvent needs to be dried and anhydrous to avoid affecting the reaction. Then, an appropriate amount of alkali, such as potassium carbonate or sodium carbonate, is added to neutralize the acidity of 2-chloroethylamine hydrochloride and promote the reaction. Then, 2-chloroethylamine hydrochloride is slowly added to the reaction system. During the reaction, pay close attention to the temperature change, and it should be maintained between room temperature and 40 degrees Celsius. After the reaction is completed, the generated salt is filtered to remove, and then the filtrate is concentrated. Subsequently, the target product 1H-pyrrole-1-ethylamine can be obtained by column chromatography.
Third, 1-acetyl pyrrole can be used as the starting material. First, 1-acetyl pyrrole is reduced. The commonly used reducing agents are lithium aluminum hydride or sodium borohydride. In a low temperature and anhydrous environment, the reducing agent is carefully added to the reaction solution containing 1-acetyl pyrrole. After the reduction reaction is completed, the product is aminated. Suitable aminating reagents, such as ammonia alcohol solution, can be selected to react under the condition of heating and reflux. After the reaction is completed, a series of post-processing operations, such as acidification, alkalization, extraction, distillation, etc., can finally obtain 1H-pyrrole-1-ethylamine. < Br >
This number method has its own advantages and disadvantages. In practical application, it is necessary to weigh the selection according to the availability of raw materials, cost, product purity requirements and many other factors to achieve the best synthesis effect.
