The common methods for synthesizing 3-amino-2-chloro-5-fluoropyridine are as follows.
One is to start with a compound containing a pyridine structure. The chlorine and fluorine atoms are introduced at the appropriate position of the pyridine ring first, which can be achieved by halogenation reaction. Select suitable halogenating reagents, such as chlorine and fluorine halogenating agents, and under appropriate reaction conditions, such as specific temperature, pressure and catalyst existence, the hydrogen atoms on the pyridine ring are replaced by chlorine and fluorine atoms. Then, through amination reaction, an amino group is introduced at a specific position in the pyridine ring. Ammonia or other amination reagents can be selected to react in a suitable reaction system to promote the amino group to replace the specific group on the pyridine ring, so as to obtain the target product 3-amino-2-chloro-5-fluoropyridine.
Second, the pyridine ring can be constructed by a multi-step reaction from a simple organic compound, and the desired amino, chlorine and fluorine atoms can be introduced at the same time. For example, a small molecule compound with a suitable functional group is used as the starting material to form a pyridine ring skeleton through condensation, cyclization and other reactions. During the reaction process, chlorine atoms, fluorine atoms and amino groups are introduced into the pyridine ring at the expected position according to the reaction conditions and the choice of reagents. Although this method has many steps, it can flexibly adjust the position and type of substituents on the pyridine ring, which is helpful for the synthesis of the target product.
