In this study, new benzo[l,2,3]thiadiazole derivatives were designed according to relationship of structure and efficacy. The 9 novel compounds were synsthesized with following reactions. The chlorine atom in 2-chloro-3,5-dinitro-benzoic acid as beginning raw material was substituted by 2-methylpropane-2-thiol, esterified then with bromoethane, reduced by iron powder and cyclized to obtain ethyl benzo[l,2,3]thiadiazole-7 after diazonation reation.
本论文根据苯并噻二唑诱导剂的构效关系设计了新的苯并噻二唑的结构，并合成了9个未见文献报道的化合物，合成步骤如下：采用2-氯-3，5-二硝基苯甲酸为起始原料，苯环上的氯原子被叔丁基硫醇置换，羧酸由溴乙烷酯化，硝基由铁粉还原，随后经重氮化关环生成苯并[1，2，3]噻二唑-7-羧酸乙酯。
