Reaction Steps
The title compound was prepared essentially as in Example 1 using anhydrous potassium fluoride (31.9 g, 0.55 mole), anhydrous dimethyl formamide (184 g), perfluoroisobutryl fluoride (112.3 g of 77% purity, 0.4 mole), and diethyl sulfate (100.1 g, 0.65 mole). The resulting mixture was worked up essentially as in Example 3 to yield 80 g of the title compound. The product identity was confirmed by IR, GCMS, and 1H and 19F NMR.
