The method of preparing 2-hydroxy-5-pyridinecarboxylic acid is a chemical preparation. There are various ways of this method, the common ones are as follows:
First, pyridine is used as the starting material. First, pyridine is substituted by an appropriate substitution reaction to introduce a carboxyl group at its 5th position. Under suitable reaction conditions, a nucleophilic substitution reaction occurs with a carboxyl-containing reagent, such as carbon dioxide, under the action of a base and a specific catalyst, and a carboxyl group is introduced at the 5th position of the pyridine ring. Subsequently, the second position of the pyridine ring is hydroxylated. A suitable oxidizing agent can be used to oxidize the hydrogen atom at the 2nd position to a hydroxyl group in a specific reaction environment. This process requires fine regulation of reaction conditions, such as temperature, pH, reaction time, etc., to obtain a product with higher yield and purity.
Second, it can also be started from derivatives containing pyridine structures. If the 5-position derivative has suitable groups that can be converted into carboxyl groups, such as ester groups, etc., it can be converted into carboxyl groups through hydrolysis. Then, for the 2-position, a suitable hydroxylation method is used, such as hydrolysis after halogenation, etc., to introduce hydroxyl groups. During halogenation, appropriate halogenation reagents and reaction conditions need to be selected to precisely replace the hydrogen atoms at the 2-position. Subsequent hydrolysis steps also require strict control of conditions to ensure that the halogen atoms are smoothly converted into hydroxyl groups without affecting the structure of the pyridine ring and the 5-position carboxyl group.
The process of preparing 2-hydroxy-5-pyridinecarboxylic acid requires chemists to carefully grasp the reaction conditions of each step, choose the preparation route reasonably according to the characteristics of the raw materials, the purity requirements of the reaction equipment and the target product, and after many tests and optimizations, satisfactory results can be obtained.
