ABSTRACT:
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.
