A 2- or 4-nitrobenzenesulfonamide is allowed to react with an alkali metal alkoxide to remove a nitrobenzenesulfonyl group to thereby obtain an amine corresponding to the amide. Furthermore, a method for producing an amine derivative by allowing the resulting amine without isolation to react with an activated, substituted oxycarbonyl compound or an activated acyl compound is provided. According to this method, a corresponding free amine and its substituted derivative can be produced easily and industrially advantageously from the 2- or 4-nitrobenzenesulfonamide without using a thiol compound.
