Procedure

The title compound was prepared essentially as in Example 3 using anhydrous potassium fluoride (6.62 g, 0.011 mole), anhydrous dimethyl formamide (800 g), C7F15COF (456.7 g, 1.09 mole), and dimethyl sulfate (14.4 g, 0.011 mole). The resulting mixture was worked up essentially as in Example 3 to give 444 g of the title compound (99.7% purity, b.=142-144° C.). The product identity was confirmed by IR, GCMS, and 1H and 19F NMR.
