176969-34-9<\/a>, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 176969-34-9 as follows.<\/p>\n

To a solution of 600 mg of 3-difluoromethyl-1-methyl-1H-pyrazole-4-carboxylic acid [compound (III)] and a catalytic amount of N,N-dimethylformamide in dichloromethane (7 mL), 450 mg of thionyl chloride were added dropwise. The mixture was refluxed for 2 h. The reaction was monitored by GC\/MS. The solvent was evaporated in vacuo. The crude acid chloride obtained was used in the following step.<\/p>\n
