Reaction Steps

A solution of 18.1 g. of 11-(pentafluoroethyl)-1-(methanesulfonyloxy)undecane and 19.8 g. of ethyl p-aminobenzoate in hexamethylphosphoramide is heated at 120° C. for 20 hours. After cooling, the reaction mixture is diluted with ethanol:water (1:1) (30 ml.) and chilled. More ethanol is added, the mixture is filtered and the solid residue is recrystallized from ethanol to yield the product as a white solid.
