Process for production of 2-alkyl-3-aminothiophene derivative
2010
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. The formula (1), the formula (3), the formula (4) and the formula (2) are shown in the description.
