A method for producing a purified amine compound represented by the formula (1), including: step (A) of reacting a crude form of the amine compound represented by the formula (1) with a hydrogen halide in the presence of water and an organic solvent insoluble in water; step (B) of separating a phase in which a hydrogen halide salt of the amine compound represented by the formula (1) produced in step (A) is dissolved from the other phase(es); step (C) of precipitating the hydrogen halide salt of the amine compound represented by the formula (1) from the phase obtained in step (B) in which the hydrogen halide salt of the amine compound represented by the formula (1) is dissolved; and step (D) of isolating the hydrogen halide salt of the amine compound represented by the formula (1) precipitated in step (C), and reacting the salt with a base.
