Sodium Iodide → 3-(4-Iodobutylsulfonylamino)-2-methoxy-1-octadecylcarbamoyloxypropane

Participants

Reaction Steps

To a solution of 1.23 g (2.22 mM) of 3-(4-chlorobutylsulfonylamino)-2-methoxy-1-octadecylcarbamoyloxypropane IIIa5 in 20 ml of methyl ethyl ketone is added 0.67 g (4.44 mM) of sodium iodide and the mixture is heated 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 (1:1) mixture as an eluent. The product is recrystallized from chloroform-n-hexane to give 1.16 g (1.79 mM) of 3-(4-iodobutylsulfonylamino)-2-methoxy-1-octadecylcarbamoyloxypropane IIa5 in 81% yield.
