A novel process for the preparation of s-triazolo[3,4-b]benzothiazole compounds comprises reacting a molar equivalent of base in an amide solvent at a temperature from 60.degree.C. to 200.degree.C. with (a) a 1-acyl-4-(o-halophenyl)thiosemicarbazide compound or (b) a 4-(o-halophenyl)-1,2,4-triazole-3-thiol compound and recovering the product. The s-triazolo[3,4-b]benzothiazole compounds are useful for the control of plant pathogens.
一种制备s-三唑并[3,4-b]苯并噻唑化合物的新工艺,包括在酰胺溶剂中以60°C至200°C的温度反应一个摩尔当量的碱和(a)1-酰基-4-(o-卤苯基)硫脲化合物或(b)4-(o-卤苯基)-1,2,4-三唑-3-硫醇化合物,并回收产物。s-三唑并[3,4-b]苯并噻唑化合物对于植物病原体的控制具有用处。
