Disclosed is a method for producing a primary amine compound represented by the formula (3) below, which is characterized in that a halogen compound represented by the formula (1) below, ammonia and formaldehyde are reacted with each other, thereby obtaining a hexahydrotriazine compound represented by the formula (2) below, and then the thus-obtained hexahydrotriazine compound is decomposed. By this method, a primary amine compound can be commercially advantageously produced by using a low-cost ammonia while suppressing production of a secondary amine as a by-product. (1) (In the formula, Ar represents an unsubstituted aromatic group such as a phenyl group, a naphthyl group, a pyridyl group, a furyl group, a thienyl group, a pyrrolyl group, an oxazolyl group, an isoxazolyl group or a pyrimidinyl group, or an aromatic group obtained by substituting such an unsubstituted aromatic group with 1-3 substituents; and X represents a halogen atom.) (2) (In the formula, Ar is as defined above.) (3) (In the formula, Ar is as defined above.) |
