Abstract: A 2-alkyl-3-aminothiophene derivative represented by general formula (4) can be produced by a production process comprising the following steps: oxidizing a compound represented by general formula (1) to produce a compound represented by general formula (3); and reducing the compound represented by general formula (3). Thus, a process for producing a 2-alkyl-3-aminothiophene derivative effectively can be provided. In the formulae, R represents an alkyl group or the like; X represents a hydroxy group, a halogen atom, or a substituent represented by general formula (2); A represents a carbon atom or a sulfur atom; Q represents an alkyl group or the like; n represents 1 or 2; and # represents a binding site.

Abstract: PURPOSE: To obtain the titled compound industrially advantageously, by using 3- or 4-nitrobenzoyl chloride and chlorobenzene as starting substances, subjecting them to three-stage processes of Friedel-Crafts reaction, nitration reaction and reduction, and dehydrochlorination.
CONSTITUTION: 3- or 4-Nitrobenzoyl chloride and chlorobenzene are subjected to Friedel-Crafts reaction in the presence of a Lewis acid catalyst to give a mixture of isomers of chloronitrobenzophenone. This compound without purification is nitrated to give a mixture of chloro-dinitrobenzophenone. This compound is reduced catalytically and dechlorinated in the presence of a reductive catalyst and a dehydrochlorinating agent, to give 3,3'- or 3,4'-diaminobenzophenone useful as a monomer for heat-resistant high polymers, intermediate for agricultural chemicals, drugs, etc. in high yield in high purity and industrially inexpensively.
