Reaction Steps
A mixture of 27-stearoyloxyheptacosanoic acid (8.88 g, 12.8 mmoles), tetrahydrofuran (120 ml), dried 1-hydroxybenzotriazole (4 g, 34.1 mmoles), phytosphingosine (3.91 g, 12.33 mmoles) and N,N'-diisopropylcarbodiimide (2.55 ml, 16.3 mmoles) was stirred under nitrogen for 2 hours at 40° C. and for another 4 hours at 50° C. After filtration and recrystallisation from hot chloroform 8.84 g of the title compound was obtained.
