What are the synthesis methods of 1- (4-Cyanophenyl) Guanidine?
The synthesis method of 1 - (4 -cyanophenyl) guanidine has been known for a long time. In the past, Fang family followed the method of organic synthesis.
First, 4-cyanoaniline is used as the starting material. First, it interacts with cyanoguanidine under suitable reaction conditions. The two meet like yin and yang symmetry. In a specific solvent, such as an alcohol solvent, add an appropriate amount of catalyst, or an acid or a base, adjust the pH of the reaction, so that the reaction environment is suitable for its reaction needs. After the step of heating and reflux, just like cooking at a moderate temperature, the molecules are intermixed and transformed, and the reaction process takes several hours or even days to obtain the initial product. However, this product or containing impurities needs to be recrystallized and carefully purified with a suitable solvent, such as ethanol-water mixed solvent, to obtain pure 1- (4-cyanophenyl) guanidine.
Second, 4-cyanobenzoic acid can also be used as a starting material. First, it is converted into the corresponding acid chloride. This process requires reagents such as sulfurous acid chloride, which can be reacted under mild conditions to convert carboxyl groups into acyl chlorides. The resulting acid chloride reacts with guanidine, and the two are combined. In an appropriate reaction medium, such as dichloromethane and other organic solvents, in the presence of acid binding agents, the alkaline environment of the reaction system is maintained, so that the reaction can proceed smoothly. After the reaction is completed, the subsequent separation and purification steps are similar to the previous method. Impurities are removed by means of extraction and column chromatography, and the final product is obtained.
The synthesis methods of the two have their own advantages and disadvantages. The former starting material 4-cyanoaniline is relatively easy to obtain, and the reaction step is relatively simple; although the latter step is slightly complicated, the starting material 4-cyanobenzoic acid used has good stability and the reaction process is easy to control. It can be used according to actual needs, availability of raw materials and reaction conditions.
