Abstract: The present invention relates to a method for producing an amino group-containing phosphate compound, by which the compound can be easily synthesized through a one-step reaction. The method for producing an amino group-containing phosphate compound comprises reacting an aminophenol compound represented by the general formula (1) with a dichlorophosphoric acid compound represented by the general formula (2): (where X1, X2, X3, X4 and X5 each represent a hydrogen atom or an alkyl group having 1 to 3 carbon atoms) in the presence of an inorganic basic compound in an aprotic organic solvent, to obtain a amino group-containing phosphate compound represented by the following general formula (3) where X1, X2, X3, X4 and X5 are defined in the same way as in the general formula (2).
