Procedure

1.402 g of dl-[trans-3-(N-heptadecylcarbamoyloxy)tetrahydropyran-2-yl]methyl 2-bromoethyl phosphate (prepared as described in Example 1f) was dissolved in a 3:5:5 by volume mixture of chloroform, isopropanol and dimethylformamide, and 7.0 g of gaseous trimethylamine were introduced into the solution. The mixture was heated, under a nitrogen atmosphere, on an oil bath kept at 50° for 6 hours, whilst stirring, and was then cooled, after which 0.483 g of silver carbonate was added The mixture was heated under reflux for 1 hour, and then the solvent was distilled off. Methanol was added to the residue and insolubles were separated by filtration. The solvent was stripped from the resulting solution by evaporation under reduced pressure. The residue was purified by liquid chromatography [using 30 g of silica gel and a Lobar column (size B)], giving 0.930 g of the title compound as a white powder from the fractions eluted with a 32:7:1 by volume mixture of methylene chloride, methanol and water.
