Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 176969-34-9, name is 3-(Difluoromethyl)-1-methyl-1H-pyrazole-4-carboxylic acid, A new synthetic method of this compound is introduced below., Product Details of 176969-34-9
Add a 1-methyl-3-difluoromethyl-1H-pyrazole-4-carboxylic acid (30.0 mmol) and 10 mL of sulfoxide to a 100 mL reaction flask, and heat to reflux. After waiting for the reaction solution to change from turbid to clear, continue to react for 30 minutes.Stop heating and concentrate to remove excess sulfoxide,1-methyl-3-difluoromethyl-1H-pyrazole-4-formyl chloride represented by the formula (V-1) was obtained, and it became a solid after cooling.
The synthetic route of 176969-34-9 has been constantly updated, and we look forward to future research findings.
