Sodium Iodide → 3-(3-Iodopropylsulfonylamino)-2-methoxy-1-octadecylcarbamoyloxypropane

Participants

Reaction Steps

To a solution of 3.845 (8.18 mM) of 3-(3-chloropropylsulfonylamino)-1-hexadecyloxy-2-methoxypropane III a3 in 30 ml of methyl ethyl ketone is added 2.45 g (16.36 mM) of sodium iodide and the mixture is refluxed for 3 hours with stirring. After the solvent is evaporated, the residue is purified by the column chromatography on silica gel with a n-hexane-ethyl acetate (4:1) mixture as an eluent. The product is recrystallied from methanol to give 3.556 g (6.332 mM) of 1-hexadecyloxy-3-(3-iodopropylsulfonylamino)-2-methoxypropane II a3 in 77% yield.
