どの問題があった。However, a method using a heavy metal oxidizing agent usually requires an oxidizing agent having a stoichiometry or more, and as a result, a waste liquid containing a large amount of heavy metal ions is generated. Improvement was needed. In addition, the synthesis by ammoxidation requires large-scale dedicated equipment and treatment of ammonia produced as a by-product after hydrolysis. In the method using ozone, hydrogen peroxide, or high-purity oxygen as the oxidizing agent, it is difficult to handle the oxidizing agent because it is gaseous or extremely unstable. However, there are inconveniences such as an increase in facility load. In the method via halogenation of a side chain methyl group, selectivity of halogenation (a distinction between a side chain methyl group and an aromatic ring) may be low, or the heterocycle itself may be oxidized under the halogenation reaction conditions. Thus, it is often difficult to obtain an intermediate halide. Further, regarding the hydrolysis of halides, the yield, reaction time, waste liquid treatment and the like were not yet satisfactory, and improvement was required. In electrochemical oxidation, there was a problem that scale-up was difficult due to the limitation of the oxidation apparatus.

After reduction and removal with sodium sulfite or the like, the pH is adjusted in consideration of the pKa of the target substance. If the desired product has low water solubility and can be extracted with an organic solvent, extraction is performed at this stage to separate the water-soluble product from the nickel compound, and the product can be purified by conventional means such as recrystallization or column chromatography. When the target substance has high water solubility and the extraction operation is difficult and the target substance is a solid, the reaction solution is concentrated and the target substance is salted out. When salting out is difficult, the reaction solution is concentrated, and a water-soluble organic solvent is added to remove as much of the by-produced inorganic salt as possible, followed by recrystallization with a water-containing solvent. If the target product cannot be isolated by the above operation, it is considered that the coexistence of the nickel compound may cause the isolation hindrance. Therefore, the nickel compound is removed by a cation exchange column and then recrystallized. When the coexistence of a small amount of inorganic salt hinders the isolation, the inorganic salt is removed by a desalting apparatus having an electrophoretic filtration membrane, and the desired product is isolated. When the target substance is a liquid, the nickel compound is removed by an ion exchange column, and the inorganic salt is removed by a desalter to isolate the target substance.
