The present invention provides a process for producing a substituted aniline compound represented by the following general formula (6): (in the formula, R<SUB>1</SUB>, R<SUB>2 </SUB>and R<SUB>3 </SUB>are each independently an alkyl group, an alkoxy group, an alkoxyalkyl group, a haloalkyl group, a carboxyl group, an alkoxycarbonyl group, an alkyl-carboxamide group, a nitro group, an aryl group, an arylalkyl group, an aryloxy group, a halogen atom or a hydrogen atom; and X and Y are each independently a hydrogen atom, an alkyl group, an alkoxy group, an alkoxyalkyl group, a haloalkyl group, a carboxyl group, an alkoxycarbonyl group or a halogen atom), characterized by oxidizing a substituted indole compound represented by the following general formula (3): (in the formula, R<SUB>1</SUB>, R<SUB>2</SUB>, R<SUB>3</SUB>, X and Y have the same definitions as given above) to give rise to the ring opening of indole ring to produce an acetanilide compound represented by the following general formula (4): (in the formula, R<SUB>1</SUB>, R<SUB>2</SUB>, R<SUB>3</SUB>, X and Y have the same definitions as given above; and Ac is an acetyl group) and subjecting this compound to reduction and deacetylation, advantageously in industry.
