Procedure

To a stirred ice-cold solution of 18.3 g. of p-(2,2,2-trifluoro-N-hexadecylacetamido)benzoic acid in 80 ml. of dioxane is added successively 4.84 g. of N-hydroxysuccinimide and 9.16 g. of dicyclohexylcarbodiimide. After 18 hours at 0°-5° C. the mixture is stirred vigorously for one hour with hexane and water and filtered. The hexane layer is washed with water, dried over magnesium sulfate, and concentrated to give an oil.
