The common methods for synthesizing 2-chloro-4-iodine-5- (trifluoromethyl) pyridine are as follows.
First, the compound containing the pyridine structure is used as the starting material, and chlorine and iodine atoms are introduced by halogenation reaction. Chlorination of the pyridine ring can be carried out at a specific position first, usually in a suitable solvent, such as dichloromethane, under the action of Lewis acid catalyst, such as aluminum trichloride, with chlorinated reagents, such as dichlorosulfoxide or phosphorus oxychloride. In this process, the reaction temperature and time need to be precisely controlled to prevent excessive chlorination. After the chlorine atom is successfully introduced, in another reaction step, in the presence of a suitable base, such as potassium carbonate, in an organic solvent such as N, N-dimethylformamide, with an iodine substitution agent, such as iodomethane or potassium iodide, the iodine atom is introduced into the target position of the pyridine ring. The key to this path lies in the precise regulation of the reaction conditions at each step to ensure the selectivity and yield of the reaction.
Second, the target compound is synthesized by constructing a pyridine ring. For example, using a suitable nitrile compound and a ketone compound containing trifluoromethyl as raw materials, under basic conditions and the action of a catalyst, a cyclization reaction occurs to form a pyridine ring. A strong base of sodium alcohol, such as sodium ethanol, can be selected to catalyze the reaction in an anhydrous ethanol solvent. After the ring is formed, the halogenation reaction is carried out in sequence, first chlorine atoms are introduced, and then iodine atoms are introduced. The halogenation reaction conditions are similar to the above, but they need to be adjusted appropriately according to the characteristics of the substrate. The advantage of this approach is that complex pyridine structures can be constructed from simple raw materials, but there are many reaction steps, and the intermediates of each reaction need to be strictly separated and purified.
Third, the coupling reaction catalyzed by transition metals is used. A compound containing a pyridine ring with a suitable leaving group (such as a bromine atom) at one end, with a chlorinated reagent and an iodine reagent, in a transition metal catalyst such as palladium catalyst (such as tetra (triphenylphosphine) palladium) and a ligand (such as tri-tert-butylphosphine), in a suitable solvent (such as toluene), under a certain temperature coupling reaction occurs. At the same time, for the introduction of trifluoromethyl, a reagent containing trifluoromethyl, such as trifluoromethylated copper reagent, can be used under a similar catalytic system. The advantage of this method is that the reaction conditions are relatively mild and the selectivity is high, but the cost of transition metal catalysts is high, and the post-reaction treatment needs to consider the problem
