الإجراء التجريبي

(2S, 3R)-2-amino-3-octadecanol (155, 750 μg, 2.6 μmol) was dissolved in dichloromethane (100 μL) to which 1,1′-carbonyldiimidazole (0.85 mg, 5.3 μmol) and triethylamine (0.4 μL, 2.9 μmol) was added. The solution was stirred for 5 h and then the solvent removed by a stream of nitrogen. The crude product 158 was analyzed without purification: IR (NaCI) 36, 2919, 2851, 1742, 1713, 1551, 1470, 1395, 1321, 49, 1239, 1094, 1061, 1001, 768, 743, 664 cm−1; FABMS m/z 785, 623, 474, 406, 362, 328, 312, 286, 268.
