Procedure
The title compound was prepared essentially as described in Example 1 by combining 5-heptyloxy-2-(4-hydroxyphenyl)pyrimidine (3.0 g, 10.0 mmol) and 3-(2-(2-(nonafluorobutoxy)tetrafluoroethoxy)-2,2-difluoroethoxy)-1-bromopropane (6.6 g, 12.0 mmol, Example 10). The product was isolated by addition of water (60 mL) to the resulting 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 Kugelrohr distillation (b.p. 180-190° C. at 2 torr; yield 5.6 g).
