To prepare 2 - (4,5 - dihydro - 4 - methyl - 4 - (1 - methylethyl) - 5 - oxo - 1H - pyrazole - 2 - yl) - 3 - picolinecarboxylic acid, the following ancient methods can be used.
Take a suitable reaction vessel and prepare it in a clean state. Add an appropriate amount of starting material to it, which needs to be carefully purified to ensure high quality. Start with 4,5-dihydro-4-methyl-4- (1-methylethyl) -5-oxo-1H-pyrazole-2-related derivatives and pyridinecarboxylic acid precursors.
Slowly add a specific organic solvent into the container. This solvent needs to have good compatibility with the reactants, and the boiling point and polarity are suitable for the reaction. Usually, N, N-dimethylformamide can be selected to create a stable reaction environment.
Next, under stirring, add an appropriate amount of catalyst. This catalyst can significantly increase the reaction rate and guide the reaction in the desired direction. For example, some metal-organic complex catalysts, the dosage is carefully adjusted to achieve the best catalytic effect.
Then, the reaction system is heated to a specific temperature range. Temperature control is extremely critical. If it is too high, side reactions will occur frequently, and if it is too low, the reaction will be slow. Generally speaking, the temperature is maintained between [X] ° C and [X] ° C, and this temperature is maintained and stirred continuously to allow the reactants to fully contact and react.
During the reaction, the reaction process needs to be closely monitored. The composition changes of the reaction mixture can be detected regularly by means of thin layer chromatography (TLC). When the raw materials are exhausted and the amount of the target product is as expected, the reaction can be regarded as complete.
After the reaction is completed, pour the reaction mixture into an appropriate amount of quencher to terminate the reaction. The product is then separated and purified. First, the target product is extracted with an organic solvent to enrich the organic phase. Then, by fine separation methods such as column chromatography, impurities are removed to obtain a pure 2 - (4,5 - dihydro - 4 - methyl - 4 - (1 - methylethyl) - 5 - oxo - 1H - pyrazole - 2 - yl) - 3 - pyridinecarboxylic acid product. The entire process requires rigorous operation and attention to detail in order to achieve the ideal yield and purity.
