In addition, there are also those who start with other nitrogen-containing heterocyclic compounds and convert to pyridine-3,4-dicarboxylic acids through multiple steps. This pathway often requires complex reaction sequences, including ring opening, ring closing, and functional group transformation. Careful operation is required at each step to ensure the purity and yield of the intermediate product before the final successful preparation of pyridine-3,4-dicarboxylic acid. These methods have their own advantages and disadvantages. In actual preparation, the optimal method is selected based on factors such as the availability of raw materials, cost, and purity requirements of the target product.
