Title:
METHOD FOR SELECTIVELY PRODUCING PRIMARY AMINE COMPOUND
Document Type and Number:
WIPO Patent Application WO/2007/069685
Kind Code:
A1
Abstract:
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.)
