Patent ID: 7652170

Claim:
A method for producing a primary amine compound represented by the formula (2): wherein R 1 and R 2 each independently represents a hydrogen atom, a straight-chain or branched C1-C5 alkyl group which may be substituted with a halogen atom, a monoalkylamino group, a di(alkyl)amino group or an amino group, a straight-chain or branched C1-C5 alkoxy group which may be substituted with a halogen atom, a cyano group, a straight-chain or branched C2-C11 alkenyl group, a straight-chain or branched C2-C11 alkynyl group, or a phenyl group which may be substituted with 1 to 3 substituents selected from the group consisting of a halogen atom, a straight-chain or branched C1-C5 alkyl group, a straight-chain or branched C1-C5 alkoxy group, a cyano group, a nitro group and C1-C3 alkylenedioxy group, and R 3 represents a hydrogen atom, a straight-chain or branched C1-C5 alkyl group or a cyano group; which comprises reacting a halogen compound represented by the formula (1): wherein R 1 , R 2 and R 3 are the same as above and X represents a halogen atom, with ammonia and formaldehyde, and then 1) bringing the thus-obtained reaction product into contact with an aqueous solution of an acid, or 2) reacting the reaction product with a hydroxylamine under acidic conditions.
