The invention intends to provide means for producing halogenated aromatic methylamine useful as an intermediate in the production of agrochemical or medical preparations, by an industrially advantageous method. The process according to the present invention for producing halogenated aromatic methylamine is characterized by comprising hydrogen-reducing a halogenated aromatic nitrile represented by formula (1): 1 (wherein X represents a chlorine atom or a fluorine atom, m represents an integer of 1 to 5, n represents an integer of 1 to 5, m+n≦6, and when n is 2 or more, each X may be the same or different) using a hydrogenating catalyst in the presence of an organic acid in a solvent to produce a halogenated aromatic methylamine represented by formula (2): 2 (wherein X, m and n have the same meanings as defined above, and a represents an integer of 1 to m).
A process for producing a halogenated aromatic methylamine, comprising hydrogen-reducing a halogenated aromatic nitrile represented by formula (1):
A catalyst used for producing halogenated aromatic methylamine represented by formula (2) from a halogenated aromatic nitrile represented by formula (1):
