Embodiment 1
[0099] 3-Difluoromethyl-1-methyl-1H-pyrazole-4-carboxy-[4-methyl-3-(2,4,5-trifluorophenyl)-3H-thiazole-2-ylidene Preparation of ]-amide (Compound No. 24)
[0100] Step 1: Synthesis of 3-difluoromethyl-1-methyl-1H-pyrazole-4-carbonyl chloride
[0101]
[0102] Add 53.00g of 3-difluoromethyl-1-methyl-1H-pyrazole-4-carboxylic acid and 72mL of thionyl chloride to a single-necked flask, raise the temperature until the system refluxes, cool after reflux for 2 hours, and evaporate at normal pressure Unreacted thionyl chloride. The temperature of the system is lowered to below 60°C, an anhydrous calcium chloride drying tower is connected externally, and the low-boiling impurities are evaporated under reduced pressure by a water pump to obtain a red viscous liquid, which solidifies into white crystals overnight. Yield 78.25%.
[0103] The NMR data of white crystals are: 1 H NMR (400MHz, CDCl 3 ),δ:3.95(s,3H,N-CH 3 ),6.97(t,J H-F =54.20Hz,1H,-CHF 2 ), 8.06 (s, 1H, pyrazolyl-H...
Embodiment 2
[0114] 2-[2-(3-Chloro-pyridine)]-5-fluoromethoxy-2H-pyrazole-3-carboxy-[4-methyl-3-(2-methyl-4-heptafluoroiso Preparation of propyl-phenyl)-3H-thiazol-2-ylidene]-amide (compound 70)
[0115]
[0116] With reference to the reaction steps in Example 1, 1-{2- [2-(3-Chloro-pyridine)]-5-fluoromethoxy-2H-pyrazole-3-carbonyl}-3-(2-methyl-4-heptafluoroisopropyl-phenyl)-sulfur Urea, then reacted with bromoacetone to obtain the target product 2-[2-(3-chloro-pyridine)]-5-fluoromethoxy-2H-pyrazole-3-carboxy-[4-methyl-3-( 2-Methyl-4-heptafluoroisopropyl-phenyl)-3H-thiazol-2-ylidene]-amide, yield: 65.2%.
Embodiment 3
[0118] 1-(4-Difluoromethoxy-phenyl)-5-isopropyl-1H-[1,2,3]triazole-4-carboxy-[3-(5-chloro-2-cyano- Preparation of phenyl)-4-methyl-3H-thiazol-2-ylidene]-amide (compound 169)
[0119]
[0120] Referring to the reaction steps in Example 1, using 1-(4-difluoromethoxy-phenyl)-5-isopropyl-1H-[1,2,3]triazole-4-carboxylic acid as raw material 1-(5-chloro-2-cyano-phenyl)-3-[1-(4-difluoromethoxy-phenyl)-5-isopropyl-1H-[1,2,3] Triazole-4-carbonyl]-thiourea, then reacted with bromoacetone to obtain the target product 1-(4-difluoromethoxy-phenyl)-5-isopropyl-1H-[1,2,3]tri Azole-4-carboxy-[3-(5-chloro-2-cyano-phenyl)-4-methyl-3H-thiazol-2-ylidene]-amide, yield: 66.3%.
