Disclosed is a simple method for efficiently producing a 3-mercaptoaniline compound which is known as an intermediate for a 3-(1H-1,2,4-triazol-1-yl)phenylsulfide derivative that is useful as a pesticide and the like. Also disclosed is a method for producing a compound which can be a raw material to be used in the method for producing a 3-mercaptoaniline compound. Specifically disclosed is a method for producing a 3-mercaptoaniline compound represented by general formula (2), which is characterized in that a nitro group and a chlorosulfonyl group of a 3-nitrobenzenesulfonyl chloride compound represented by general formula (1) are reduced in the presence of an acid catalyst. Also specifically disclosed is a method for producing a compound which can be a raw material to be used in the method for producing a 3-mercaptoaniline compound. (1) (In the general formula (1), R represents an alkyl group or a cyclic alkyl group, and X represents a halogen atom.) (2) (In the general formula (2), R and X are as defined above.)
