Reaction Steps

The title compound was prepared essentially as in Example 1 by combining 5-octyl-2-(4-hydroxyphenyl)pyrimidine (1.04 g, 3.64 mmol) and 2-(6-(2-(nonafluorobutoxy)tetrafluoroethoxy)-2,2,3,3,4,4,5,5,6,6-decafluorohexyloxy)-1-p-toluenesulfonyl ethane (3.36 g, 4.05 mmol; prepared by combining ethylene carbonate and 6-(2-(nonafluorobutoxy)tetrafluoroethoxy)-2,2,3,3,4,4,5,5,6,6-decafluorohexanol and then preparing the p-toluenesulfonate from p-toluenesulfonyl chloride. The resulting crude product was isolated and further purified essentially as described in Example 3, eluting with ethyl acetate/hexane, to yield 2.88 g of purified product.
