The title compound was prepared essentially as in Example 1 by combining 2-(2-(2-(2-(nonafluorobutoxy)tetrafluoroethoxy)-2,2-difluoroethoxy)ethoxy)ethyl bromide (7.7 g of 90% purity by gas chromatography 11.8 mmol) with 5-hexyloxy-2-(4-hydroxyphenyl)pyrimidine (3.0 g, 11.0 mmol). The resulting product was isolated by addition of water (50 mL) to the reaction mixture, followed by filtration and recrystallization from ethanol. The recrystallized precipitate was dried at about 130° C., and the resulting product was further purified by distillation using a Kugelrohr apparatus (b.p. 185-210° C. at 0.01 torr; yield 5.6 g).
