Preparation method of 2-[(N-4-chlorophenyl)-3-pyrazolyloxymethyl]nitrobenzene

The invention belongs to the technical field of fine chemical engineering and particularly relates to a preparation method of 2-[(N-4-chlorophenyl)-3-pyrazolyloxymethyl]nitrobenzene. The preparation method comprises the following steps: reacting in the presence of an alkaline reagent and a phase transfer catalyst by taking 1-(4-chlorophenyl)-3-hydroxypyrazole and nitrobenzyl bromide as raw materials and a mixed solution consisting of water and an organic solvent as a reaction solvent; after the reaction is finished, cooling, carrying out suction filtration, and drying to obtain the product. According to the preparation method, the after-treatment is simple, and re-crystallization and washing are omitted. Compared with the prior art, the preparation method has the advantages that the product quality is good, the yield is high, and the reaction period is short, so that the preparation method has wide industrial application prospects.
