The title compound was prepared essentially as in Example 1 by combining 4-(2-(2-(2-(trifluoromethoxy)tetrafluoroethoxy)tetrafluoroethoxy)-2,2-difluoroethoxy) 1-bromobutane (6.1 g, 15.0 mmol, Example 25) with 5-heptyloxy-2-(4-hydroxyphenyl)pyrimidine (3 g, 10.5 mmol). The resulting crude product was further purified by recrysallization from ethanol and subsequent Kugelrohr distillation (b.p. 200°-210° C. at 0.3 torr; yield of 5.2 g).
