FIELD: industrial organic synthesis.
SUBSTANCE: process comprises hydrogen reduction of halogenated aromatic nitrile represented by general formula 1:
in which X denotes chlorine or fluorine atom, m integer from 1 to 5, n integer from 1 to 5, and m+n ≤ 5, provided than when n≥ 2, all X can be the same or different, using hydrogenation catalyst selected from group consisting of optionally modified porous nickel and optionally modified porous cobalt and in presence of organic acid in solvent to form halogenated aromatic methylamine represented by general formula 2: , in which X, m, and n are as defined above and "a" is integer from 1 to m).
EFFECT: enabled efficient large-scale production of desired product with high output.
