Paragraph 0028-0029; 0032, (2021/06/26)
The invention discloses a preparation method of a substituted phenoxy benzylamine compound. P-halobenzonitrile is taken as an initial raw material, R'OH is taken as a solvent in the presence of R'OM, the substituted phenoxy benzylamine compound is obtained through hydrogen reduction, and the preparation method has the advantages of high yield and high purity. The invention also discloses a preparation method of pyrazole carboxamide. The preparation method of pyrazole carboxamide comprises the following steps: salifying the substituted phenoxy benzylamine compound, and reacting with a substituted pyrazole acyl chloride compound to prepare the pyrazole carboxamide compound at an expected high yield. The preparation methods provided by the invention have the advantages of high product purity, high yield, low solvent loss and low production cost.

A series of original pyrimidinamine derivatives containing a biphenyl ether moiety were designed and synthesized. Their structures were confirmed by 1H NMR, MS, and elemental analyses. Their insecticidal activities against lepidopteran and hemiptera insects and acaricidal activities were tested. The results of bioassay demonstrated that 9k showed the best activity (LC50 = 2.08 mg/L) against Tetranychus urticae, which is comparable with the positive control, spirotetramat (LC50 = 2.27 mg/L), and 9g showed better activity (LC50 = 0.52 mg/L) against Aphis fabae than the positive control, imidacloprid (LC50 = 1.02 mg/L), and relatively good activity (LC50 = 2.49 mg/L) against T urticae. Their structure-activity relationships indicated that both an ethyl group on the 4-position of the pyrimidine ring and alkyl chain as a para-substituent group of the benzene ring showed good biological activity.
