PROBLEM TO BE SOLVED: To provide a new method for industrially advantageously preparing 1,5-diaminonaphthalene which does not by-produce a 1,8-diamino isomer and does not go through a relatively unstable nitroimine/nitroenamine as an intermediate. SOLUTION: 5-Nitro-1-tetralone is halogenated and dehydrohalogenated to be aromatized without using a large amount of a noble metal catalyst, and then reduced and aminated to industrially advantageously prepare 1,5-diaminonaphthalene.
