The synthesis method of 5-ol-6-chloro-2- (trifluoromethyl) pyridine is not directly recorded in the classic "Tiangong Kaiwu", but it can be found by extrapolating from ancient chemical techniques and synthesis ideas.
Synthesis of such compounds in the past, or a step-by-step reaction method. The first choice of raw materials should be based on basic substances containing chlorine, fluoromethyl and pyridine structures. If a specific halogenated pyridine derivative is used as the starting material, its halogen atom can be used as a key activity check point in the subsequent reaction.
In the reaction step, or through the nucleophilic substitution reaction, the hydroxyl (-OH) functional group is introduced. The choice of nucleophilic reagents is very important. In the past, reagents with suitable nucleophilic properties, such as trifluoromethyl reagents, are often fused with halogenated pyridine derivatives under appropriate solvents and reaction conditions. For example, choose an alcohol solvent and control it at a moderate temperature, or allow nucleophilic substitution to occur smoothly, so that halogen atoms are gradually replaced by hydroxyl groups to form hydroxyl-containing pyridine intermediates.
Furthermore, the introduction of trifluoromethyl groups is a difficult step and requires fine control. In the past, reagents containing trifluoromethyl groups, such as trifluoromethylation reagents, were used to react with the above intermediates with the assistance of catalysts. The catalyst can promote the reaction activity, so that the trifluoromethyl group can be effectively connected to the specific position of the pyrid
The control of reaction conditions is crucial. Temperature, pressure, and reaction time all need to be precisely adjusted. For example, in the early stage of the reaction, the reaction rate should be controlled at low temperature to prevent side reactions from occurring; in the middle of the reaction, the temperature should be gradually increased to promote the reaction to generate the target product; in the later stage of the reaction, according to the reaction process, the temperature should be cooled in a timely manner, and the reaction should be terminated to ensure the stability of the product.
