The synthesis method of 2-chloromethyl-3-methyl-4- (2,2,2-trifluoroethoxy) pyridine hydrochloride is not contained in the ancient book "Tiangong Kaiwu", but the chemical technology ideas contained in it can be learned. The common synthesis paths described above are as follows.
First, 3-methyl-4-hydroxypyridine is used as the starting material, which is the foundation of the synthesis. It is co-placed with an appropriate base, such as potassium carbonate, in a suitable organic solvent, such as N, N-dimethylformamide (DMF), and stirred evenly to make the system appear in an alkaline environment. This is the foundation for the subsequent reaction. The action of the alkali, as in ancient books, is based on the principle that the phase of matter is different, and the environment is adjusted to start the reaction.
Then, slowly add 2,2,2-trifluoroethyl halide, such as 2,2,2-trifluoroethyl bromide. The halide is like an introduction, which stimulates the reaction to move forward. Temperature-controlled reactions, such as the control of the fire conditions in ancient books of alchemy, the reaction is overheated when the temperature is high, and the reaction is slow when the temperature is low. Generally between 50 and 80 ° C. When the reaction number is high, the intermolecular interaction, the hydroxy group and the trifluoroethoxy group are transposed to obtain 3-methyl-4- (2,2,2-trifluoroethoxy) pyridine.
Then the chloromethylation reagent is prepared by the interaction of paraformaldehyde with hydrogen chloride gas in a specific solvent, such as dichloromethane. This step is like the ancient method of processing and careful preparation. Then, 3-methyl-4- (2,2,2-trifluoroethoxy) pyridine is added to this system, and the chloromethylation reagent such as Lingyin introduces chloromethyl groups into the pyridine ring to generate 2-chloromethyl-3-methyl-4- (2,2,2-trifluoroethoxy) pyridine.
Finally, the product is reacted with hydrogen chloride gas or hydrochloric acid solution to form a salt to obtain 2-chloromethyl-3-methyl-4- (2,2,2-trifluoroethoxy) pyridine hydrochloride. Each step of the reaction requires precise control conditions, such as ancient man-made devices, to obtain the desired product.
