What are the preparation methods of 4-chloro-3- (3-methyl-5-oxo-2-pyrazolin-1-yl) benzenesulphonic Acid
The preparation method of 4-chloro-3- (3-methyl-5-oxo-2-pyrazoline-1-yl) benzenesulfonic acid has the following methods:
First, it can be prepared by condensation reaction between chlorobenzenesulfonic acid derivatives and specific pyrazoline compounds. First, take an appropriate amount of chlorobenzenesulfonic acid, place it in a clean reactor, and add an appropriate amount of organic solvent, such as dichloromethane, N, N-dimethylformamide, etc., to help dissolve and disperse uniformly. Warm up to an appropriate temperature, usually at 50-80 ° C. Slowly add a solution of 3-methyl-5-oxo-2-pyrazoline dropwise, and continue to stir during the dropwise addition process to promote full contact between the two. After dropping, when the reaction is continued at this temperature, the reaction process needs to be closely monitored during this period, and the degree of reaction can be judged by means of thin layer chromatography. When the reaction is complete, cool the reaction solution to room temperature, neutralize it with an appropriate alkali solution, such as sodium hydroxide solution, adjust it to neutral or weakly alkaline, and then remove the organic solvent through extraction, separation, distillation, etc., to obtain a crude product. Subsequent refining methods such as recrystallization can obtain a pure target product.
Second, it can also be prepared by the strategy of constructing pyrazoline rings. First, a suitable benzenesulfonic acid derivative is used as the starting material, and a group capable of constructing pyrazoline rings is introduced under appropriate conditions. For example, the benzenesulfonic acid derivative is reacted with 3-methyl-1,2-dione compounds and hydrazine compounds under acid catalysis. Put the benzenesulfonic acid derivative, 3-methyl-1,2-dione and hydrazine into the reaction vessel in a certain proportion, add an appropriate amount of acidic catalyst, such as p-toluenesulfonic acid, and react under reflux conditions with ethanol or ethyl acetate as the solvent. After the reaction is completed, the system is cooled, the insoluble matter is filtered and removed, the filtrate is concentrated by reduced pressure distillation, and then recrystallized with an appropriate solvent to obtain the target product 4-chloro-3- (3-methyl-5-oxo-2-pyrazoline-1-yl) benzenesulfonic acid.
During the preparation process, attention should be paid to the precise control of the reaction conditions, including temperature, pH, reactant ratio, etc., to improve the yield and purity of the product. And each step should follow the standard chemical experimental procedure to ensure safety.
