The reaction of hexadecanol (I) with the cyclic chlorophosphate ester (II) and DIEA in dichloromethane gives the cyclic hexadecyl phosphate (III), which is brominated with Br2 in the same solvent to yield the mixed 2-bromoethyl hexadecyl bromophosphate ester (IV). Finally this compound is condensed with trimethylamine in acetonitrile/isopropanol/chloroform to furnish the target phosphorylcholine ester.
