The invention relates to a method for preparing aminonaphthol compounds. The method refers to adding catalysts, aldehyde compounds, secondary amine compounds and naphthol into water in sequence, and reacting at a temperature of 20-80°C. The reaction solution is obtained after completeness; the reaction solution is successively extracted, dried, concentrated, and separated by column chromatography according to conventional methods to obtain product I or product II, and the product structural formula is as follows: . The invention has mild conditions, short reaction time, simple aftertreatment, high yield, environmental protection, large-scale production can be realized, and good industrial application prospect. |
