A method for synthesizing a 2-alkanoylamino-4-nitrophenyl phosphorylcholine-hydroxide useful as a sphingomyelinase-specific chromogenic artificial substrate in the diagnostic testing for Niemann-Pick disease. The method comprises reacting 2-amino-4-nitrophenol with an alkanoyl halide to form the alkananilide; phosphorylating the alkali phenolate salt of the alkananilide with β-bromoethylphosphoryl dichloride to form a mixture of mono- and di-alkananilide phosphoric acid esters; recovering from the mixture the mono-alkananilide phosphoric acid ester and quaternizing it with trimethylamine; and treating the resulting quaternary salt with a mixture of weak acidic and weak basic ion exchange resins to convert it into the 2-alkanoylamino-4-nitrophenyl phosphoryl-choline-hydroxide.
