The synthesis method of 2-chloro-6- (4-fluorophenyl) pyridine-3-formonitrile has been known for a long time, and it has become more and more abundant and complete with the changes of time. The following are several common methods:
First, the compound containing the pyridine structure is used as the starting material. The chlorine atom is introduced at a specific position in the pyridine ring first, which can be achieved by halogenation reaction. Subsequently, 4-fluorophenyl is connected to the corresponding check point of the pyridine ring through reactions such as nucleophilic substitution. Finally, the cyanylation reaction introduces the methonitrile group at the 3 position of the pyridine ring. In this process, the halogenation reaction requires the selection of suitable halogenated reagents, such as chlorine-containing reagents, under appropriate reaction conditions, the introduction of chlorine atoms is precisely realized, and other check points of the pyridine ring are not affected. In the nucleophilic substitution reaction, factors such as reactant activity, reaction solvent and catalyst need to be considered to promote the smooth integration of 4-fluorophenyl. In the cyanation step, the selection of cyanylation reagents and the control of reaction conditions are very important, which are related to the efficiency and purity of the introduction of formonitrile groups.
Second, the strategy is to construct a pyridine ring. Select suitable starting materials and gradually build a pyridine ring structure through multi-step reactions. At the same time or after the construction of the pyridine ring, chlorine atoms, 4-fluorophenyl groups and formonitrile groups are introduced in an orderly manner. For example, fluorobenzene derivatives and chlorine and cyanyl-containing pyridine ring construction reagents can be used to construct the pyridine ring by cyclization reaction under a series of reaction conditions, and the target substituent can be introduced simultaneously or step by step. This path requires a thorough understanding of the reaction mechanism of pyridine ring construction, precise control of the reaction process and product selectivity at each step, and the introduction sequence and reaction conditions of each substituent need to be carefully designed to prevent side reactions from occurring and ensure the formation of the target product.
Third, the reaction is catalyzed by transition metals. Transition metal catalysts have unique advantages in organic synthesis. Transition metals can be used to catalyze the coupling reaction of halogenated aromatics and pyridine derivatives to realize the connection of 4-fluorophenyl groups to pyridine rings. At the same time, methonitrile groups can also be introduced through the cyanylation reaction catalyzed by transition metals. Such methods require screening suitable transition metal catalysts and their ligands, optimizing reaction conditions, such as reaction temperature, reaction time, type and dosage of bases, etc., in order to improve the reactivity and selectivity, so that each step of the reaction can be carried out efficiently, and high-purity 2-chloro-6- (4-fluorophenyl) pyridine-3-formonitrile products can be obtained.
