| Abstract: | A useful method of synthesis of the dye intermediate is presented. Reaction of 2-cyano-4-nitroaniline with hydrogen sulfide (or ammonium sulfide) to give.2-amino-5-nitro-phenylthioformamide. In the basic solution,oxidation of the thioformamide with hydrogen peroxide afforded 3-amino-5-nitro-2, 1-benzoisothiazole. |
