Reaction Steps
A solution of 45 g. of (pentadecafluoroheptyl)(trifluoromethanesulfonyloxy)methane and 28 g. of ethyl 4-aminobenzoate in 50 ml. of hexamethylphosphoramide is stirred at 120° C. for 72 hours, diluted with water, and filtered. A methylene chloride solution of the solid is dried over anhydrous magnesium sulfate and evaporated. The residue is recrystallized from acetonitrile to yield the product as a white solid.
