Title: Method for producing 1,5-diaminonaphthalenes
Inventor: INOKI SATORU
IPC: C07C255/35
Filed: 2002-04-30
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing 1,5-diaminonaphthalenes, capable of economically excellently conducting their production, by developing a new route through which the 1,5-diaminonaphthalenes are selectively produced without being accompanied with formation of their isomers. SOLUTION: This method for producing the 1,5-diaminonaphthalene comprises reacting an o-alkylnitrobenzene compound with a vinyl compound in the presence of a base so as to obtain an aromatic nitro compound. The aromatic nitro compound is subjected to ring closure in the presence of a strong acid so as to obtain a 5-nitro-1-tetralone compound. The 5-nitro-1-tetralone compound is reacted with an amine compound, then reduced and aromatized, so that the 1,5-diaminonaphthalene is produced.
