以N-吡啶基吡唑甲酸乙酯、取代邻氨基苯甲酸为原料，经由还原、氧化、亲核加成、缩合、重氮化等多步反应，合成了一系列3-（（（3-溴-1-（3-氯吡啶-2-基）-1H-吡唑-5-基）亚甲基）氨基）取代苯并[d][1，2，3]三嗪-4（3H）-酮类目标化合物.初步生物活性测试结果表明，该系列化合物大多具有一定的杀虫活性，其中一个化合物在200 mg·L-1浓度下对东方粘虫（Mythimna separata Walker）具有70%的致死率；部分化合物表现出显著的抑菌活性，有两个化合物在50 mg·L-1浓度下对苹果轮纹病菌（Physalospora piricola）具有92.3%的抑制率，可作为新型抑菌先导结构，为后续的深入研究提供重要参考.

A series of 3-(((3-bromo-1-(3-chloropyridin-2-yl) -1H-pyrazol-5-yl) methylene) amino) substituted-benzo[d] [1,2,3]-triazin-4(3H) -ones were synthesized successfully with ethyl N-pyridylpyrazole carboxylate and substituted aminobenzoic acids as starting materials, via multi-step reactions of reduction, oxidation, nucleophilic addition, condensation and diazotization. The preliminary bioassay tests indicated that most of these compounds have certain insecticidal activities, among which one compound showed a mortality rate of 70% towards Mythimna separata Walker at the test concentration of 200 mg·L-1, some compounds exhibited favorable fungicidal activities at 50 mg·L-1, particularly two compounds which possessed 92.3% growth inhibitory rate against Physalospora piricola, could be used as new fungicidal leading structures for further investigations on this type of compounds.
