Patent ID: 7271263

Claim:
A process for producing a substituted aniline compound represented by the following general formula (6): wherein R 1 , R 2 and R 3 are each independently an alkyl group, an alkoxy group, an alkoxyalkyl group, a haloalkyl group, a carboxyl 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, or a halogen atom, the process comprising: oxidizing a substituted indole compound represented by the following general formula (3): wherein, R 1 , R 2 , R 3 , X and Y have the same definitions as given above to give ring opening of the indole ring to produce an acetanilide compound represented by the following general formula (4): wherein, R 1 , R 2 , R 3 , X and Y have the same definitions as given above; and Ac is an acetyl group; and subjecting compound (4) to reduction and deacetylation to give compound (6).
