| description | The invention relates to the technical field of chemical pharmacy, in particular to an isoxazoline compound as well as preparation and application thereof. The preparation method comprises the following steps: firstly, dissolving 2-methyl-4-formaldoxime methyl benzoate, then carrying out chlorination reaction on the dissolved 2-methyl-4-formaldoxime methyl benzoate and N-chlorosuccinimide, then transferring to room temperature, adding 1, 3-dichloro-5-(1-trifluoromethyl-vinyl) benzene, and carrying out cyclization reaction to obtain a first intermediate; dissolving sodium hydroxide and the first intermediate, and reacting to obtain a second intermediate; dissolving the second intermediate and thionyl chloride, uniformly mixing, dropwise adding N, N-dimethylformamide, and reacting to obtain a third intermediate; finally, dissolving the third intermediate, dropwise adding the third intermediate into the first solution to carry out a first reaction, then adding a lithium hydroxide solution, and carrying out a sec |
