Procedure
To a stirred solution of 1.65 g. of ethyl p-aminobenzoate and 1.6 ml. of pyridine in 5 ml. of dichloromethane at 0° C. is added a solution of 4.75 g. of p-(2,2,2-trifluoro-N-hexadecylacetamido)benzoyl chloride in 10 ml. of dichloromethane. After 20 hours at ambient temperature the solution is diluted with dichloromethane and washed with water and sodium bicarbonate solution. The residue obtained on evaporation of solvent is recrystallized from hexane-ether to give a white, crystalline solid, m.p. 91°-93° C.
