Reaction Steps

A solution of 3.26 g. of 2,3-dihydroxypropyl-4-(n-hexadecylamino)benzoate and 0.85 ml. of acetic anhydride in 50 ml. of chloroform is heated to reflux for 1 hour and then cooled. The mixture is washed with 90 ml. of water and the solid at the interface filtered. The chloroform layer on concentration in vacuo gives a residue which on trituration with methylene chloride yields a white solid (starting material) after filtration. The filtrate on concentration in vacuo yields a pale yellow oil. The oil is stirred overnight with water, extracted with chloroform and azeotroped free of acetic acid with benzene. The pale yellow oil obtained by evaporation in high vacuum is then chromatographed to remove a trace of N,O-diacetylated material. The liquid product is characterized by elemental analyses, infrared spectrum and nuclear magnetic resonance.
