The method of preparing 3,6-difluoro-2-pyridinecarboxylic acid has been around for a long time. One method is to use a suitable pyridine derivative as the starting material. First, take a specific pyridine substrate, add an appropriate amount of halogenated reagent in a suitable reaction vessel, and this halogenated reagent needs to be able to introduce fluorine atoms, such as fluorine-containing halogenating agents, and carefully control the temperature to make the reaction system reach a certain temperature range, often around tens of degrees Celsius. After several hours or even longer of reaction, fluorine atoms can gradually replace hydrogen atoms at the corresponding positions on the pyridine ring to obtain fluorine-containing pyridine intermediates.
Then, the intermediate is carboxylated. This intermediate is placed in a new reaction environment, and a carboxylating agent, such as carbon dioxide or its equivalent, is added. With the help of a specific catalyst, under certain pressure and temperature conditions, the carboxyl group is then introduced into the 2-position of the pyridine ring to obtain 3,6-difluoro-2-picolinecarboxylic acid. During this process, the pressure or several atmospheres are required, and the temperature is also adjusted according to the characteristics of the reagents and catalysts used.
Another method is to start from the pyridine parent body, and first use a special fluorination method to introduce fluorine atoms into the 3,6-position of the pyridine ring at the same time. This fluorination step may require a specific fluorination catalyst and a specific reaction medium to ensure the selectivity of the fluorination reaction. After obtaining the product of difluoropyridine, a carboxyl group is constructed at the 2-position through a series of reactions such as oxidation and substitution. If some oxidation reagents are used to oxidize the specific substituent at the 2-position to a carboxyl group, or the original group at the 2-position is replaced by a carboxyl group through a nucleophilic substitution reaction, 3,6-difluoro-2-pyridinecarboxylic acid can also be obtained. All these methods require the experimenter to carefully control the reaction conditions and pay attention to the details of each step in order to obtain a pure product.
