The invention relates to a method for preparing 99 percent of 2,6-dichloro-4-trifluoromethyl phenylamine, which includes the following two steps of reaction: (1) amination reaction: 3,4-dichloro-5-nitrobenzotrifluoride reacts with ammonia to generate 3--chloro-4-amino-5-nitrobenzotrifluoride; (2) chlorination reaction: 3--chloro-4-amino-5-nitrobenzotrifluoride reacts with chlorine to generate 2,6-dichloro-4-trifluoromethyl phenylamine. The advantages of the invention are as follows: the target product 2,6-dichloro-4-trifluoromethyl phenylamine is prepared with 3,4-dichloro-5-nitrobenzotrifluoride as a material; the specific implementation route includes amination and chlorination, only simple distillation or steam distillation is needed, 99 percent of target product can be obtained without rectification, and the method has the advantages of mild reaction conditions, high safety and high product content; the process is suitable for mass industrial production, pollution is little, energy is saved, and the environment is protected.

New N-thiadiazolylanilines were designed and synthesized to develop mitochondrial cytotoxins superior to SF 6847. The mitochondrial cytotoxin N-thiadiazolylanilines, TX-108 and TX-109, inhibited EMT6/KU mammary sarcoma cell growth at a low micromolar concentration. Their inhibitory activities were parallel to their mitochondrial cytotoxicity, such as uncoupling oxidative phosphorylation and inhibiting ATP synthesis. This report also supports the notion that the inhibition of tumor cell growth of inhibitor of protein tyrosine kinase AG17, which is identical to SF 6847, may be due to its mitochondrial cytotoxicity.

The title reactions give 1-hydroxy-4-methylquinoxaline-2,3-diones (4) together with a variety of mono- and bi-cyclic byproducts. All of these may result from a common intermediate, viz. a 1-hydroxy-4-methyl-3,4-dihydro-1H-2,1,4-benzoxadiazine-3-carboxylat
