Abstract

Herbicidal ratings: 0= no effect; 5= completely killed. methyl-3-thiosemicarbazide according to the knownmethod. 5) S-Methylation of compound 2 with methyl iodide in the presence of aqueous sodium hydroxide furnished the corresponding 3-dimethylamino-4-methyl-4i/-[l, 2, 4] triazino [5, 6-Z?] indoles (3). Ammonolysis of compound 3a with dimethylamine in pyridine effected the removal of the methylthio group to give 3-dimethylamino-4-methyl-4//-[l, 2, 4] ...
