Procedure

To a mixture of glycerol (30 g, 326 mmol) and pyridine (25 ml) dissolved in DMF (300 ml) was added dropwise stearoyl chloride (10 g, 33 mmol) dissolved in DMF 100 ml9. The mixture was cooled on an ice bath until addition was complete, whereupon the reaction was maintained under an N2 atmosphere overnight. After 15 hours CH2CL2 (300 ml) and saturated NaHCO3 (aq) was added. The phases were separated and the organic phase washed with water (50 ml) and dried with Na2SO4.
