摘要:
There are provided a 4-(trichloromethylthio)aniline represented by the general formula (II): wherein R1 represents a hydrogen atom or an alkyl group having 1 to 3 carbon atoms, R2 each independently represents a halogen atom, an alkyl group having 1 to 3 carbon atoms, or a perfluoroalkyl group having 1 to 3 carbon atoms, R3 represents a formyl group, an acetyl group, or a trifluoroacetyl group, and m represents an integer of 0 to 4, a method for producing the same, and a method for producing a 4-(trifluoromethylthio)aniline derivative using the 4-(trichloromethylthio)aniline. It becomes possible to produce a 4-(trifluoromethylthio)aniline with a high yield by using raw materials that can easily be obtained industrially and using general purpose production facilities.
