To prepare 4- [5- (4-methylbenzyl) -3-trifluoromethyl) -1H-pyrazolyl] benzenesulfonamide, there are many synthesis methods. The details are as follows:
First take appropriate starting materials, such as aromatics and pyrazoles containing corresponding substituents. The aromatic hydrocarbon can be halogenated to introduce halogen atoms, which can be bromine or chlorine, depending on the reaction conditions and raw material activity. Taking bromination as an example, under the action of light or initiator, a radical substitution reaction with bromine can occur, and bromine atoms can be introduced at suitable positions of aromatics, which lays the foundation for subsequent nucleophilic substitution reactions.
In addition, pyrazole derivatives containing specific substituents are prepared. Usually, carbonyl-containing compounds and hydrazine compounds are used as raw materials, and in appropriate solvents, such as ethanol, dichloromethane, etc., under the catalysis of acid or base, the condensation cyclization reaction forms pyrazole rings. For example, acetylacetone and phenylhydrazine are heated and refluxed under the catalysis of glacial acetic acid to obtain pyrazole derivatives. The derivative needs to have an activity check point for the reaction with the aforementioned halogenated aromatics.
Subsequently, the halogenated aromatics are coupled with pyrazole derivatives. Palladium-catalyzed coupling reactions, such as Suzuki coupling or Stille coupling, can be selected. Taking Suzuki coupling as an example, halogenated aromatics, pyrazole borate derivatives, palladium catalysts (such as tetra (triphenylphosphine) palladium) and bases (such as potassium carbonate) are heated and stirred in an organic solvent (such as toluene-ethanol-water mixed solvent), and through metal transfer and reduction elimination steps, a carbon-carbon bond is formed, and the aromatics are connected to the pyrazole moiety.
Furthermore, the resulting linking product is sulfonamated. First, a sulfonyl chloride group is introduced into the benzene ring in an appropriate way, which can be achieved by the reaction of the benzene ring with sulfonating reagents such as chlorosulfonic acid. Subsequently, the sulfonyl chloride is reacted with ammonia or amine compounds to obtain a sulfonamide structure. If ammonia gas is introduced into the organic solution containing sulfonyl chloride and the reaction temperature and time are controlled, sulfonamidation can be achieved, and the final product 4- [5- (4-methylbenzyl) -3-trifluoromethyl) -1H -pyrazolyl] benzenesulfonamide can be obtained.
During the synthesis process, attention should be paid to the precise control of reaction conditions, such as temperature, pH, reaction time, etc., and the separation and purification of intermediate products is also crucial. Column chromatography, recrystallization and other means are often used to ensure the purity and yield of the product.

4- [5- (4-methylphenyl) -3-trifluoromethyl-1H-pyrazolyl] phenylboronic acid should be paid attention to the following numbers during storage and transportation:
First, this material has high chemical activity and is extremely sensitive to environmental factors. When storing, it must be selected in a cool, dry and well-ventilated place, away from fire, heat and oxidants. Because of its violent reaction with strong oxidants, it is dangerous to cause ignition and explosion. During transportation, it is also necessary to ensure that the environment is stable, avoid sudden temperature changes and excessive humidity, in order to prevent chemical reactions from triggering, damaging the purity and stability of the substance.
Second, the substance has certain toxicity and irritation. When operating, be sure to take protective measures, such as wearing appropriate protective gloves, goggles and gas masks, to prevent direct contact with the skin, eyes, or inhalation of its dust and volatiles. If you come into contact accidentally, you should immediately rinse with plenty of water and seek medical treatment according to the specific situation. During transportation, you should also follow the relevant hazardous chemical transportation regulations to ensure that the packaging is in good condition and prevent leakage from causing harm to people and the environment.
Third, packaging and labeling are essential. The packaging used for storage and transportation must be solid and durable, which can effectively prevent leakage and damage. Key information such as the name of the substance, chemical properties, hazardous characteristics and emergency treatment methods should be clearly marked on the outside of the packaging, so that relevant personnel can know and respond. During transportation, it is necessary to strictly follow the established route and time to avoid unnecessary stops and transit and reduce risks.
Fourth, the storage and transportation environment should comply with regulatory requirements. Enterprises and practitioners must strictly follow national and local regulations on the storage and transportation of hazardous chemicals, establish and improve management systems and emergency plans. Regularly check and maintain storage facilities and transportation equipment to ensure safety and reliability. In the event of a leak or other accident, emergency plans can be quickly activated to reduce losses and hazards.
