example 1
[0043] Example 1: N-(4-chloro-2-methyl-6-(methylcarbamoyl)phenyl)-1-(4-trifluoromethyl-2-thiazolyl)-3-trifluoromethyl- 1H-pyrazole-5-carboxamide
[0044] 3-trifluoromethyl-1-(4-trifluoromethyl-2-thiazolyl)-1H-pyrazole-5-carboxylic acid (6mmol) was placed in a 100 mL two-necked flask, and 50 mL of anhydrous dichloro Methane and 2 drops of DMF. Afterwards, the reaction was placed in an ice bath, and oxalyl chloride (15 mmol) was slowly added dropwise at 0° C. After 20 min, the addition was completed, and stirred at room temperature for 2 h. After TLC confirmed that the reaction was complete, the solvent was removed under reduced pressure to obtain 3-trifluoromethyl-1-(4-trifluoromethyl-2-thiazolyl)-1H-pyrazole-5-yl chloride, which was sealed and stored.
[0045] In a 100 mL three-necked flask, the acid chloride (6 mmol) prepared above was dissolved in a mixed solution of 45 mL of anhydrous N,N-dimethylformamide and 15 mL of anhydrous pyridine, and stirred at 70° C. for 30 min....

[0047] Example 2: N-(4-chloro-2-methyl-6-(isopropylcarbamoyl)phenyl)-1-(4-trifluoromethyl-2-thiazolyl)-3-trifluoromethyl -1H-pyrazole-5-carboxamide
[0048] The above preparation of 6-chloro-8-methyl-2-(3-trifluoromethyl-1-(4-trifluoromethyl-2-thiazolyl)-1H-pyrazol-5-yl)-4H- 1,3-Benzoxazinone (2.0mmol) was placed in a 50mL two-necked reaction flask, 25mL N,N-dimethylacetamide was added, and then isopropylamine (6.0mmol) was slowly added dropwise, stirred at room temperature for 2h, filtered, The filter cake was dried to obtain the target product N-(4-chloro-2-methyl-6-(isopropylcarbamoyl)phenyl)-1-(4-trifluoromethyl-2-thiazolyl)-3-tri Fluoromethyl-1H-pyrazole-5-carboxamide, the yield is 89.1%.
