Cholesteryl phosphorodichloridate is best prepared by the action of phosphoryl chloride on cholesterol in the presence of triethylamine. Chromatography and thermal decomposition of the phosphorodichloridate are briefly discussed. Cholesteryl, lanosteryl, and ergosteryl phosphorodichloridates have been treated with selected primary and secondary amines. In all cases nucleophilic substitution at the
