Reaction Steps

The title compound was prepared essentially as in Example 1 by combining 4-(2-(2-(2-(trifluoromethoxy)tetrafluoroethoxy)tetrafluoroethoxy)-2,2-difluoroethoxy) 1-bromobutane (20.9 g, 38.5 mol; prepared from 1,4-dibromobutane and 2-(2-(2-(trifluoromethoxy)tetrafluoroethoxy)tetrafluoroethoxy)-2,2-difluoroethanol) with 5-octyl-2-(4-hydroxyphenyl)pyrimidine (10.0 g, 0.35 mol). The resulting product was further purified by recrystallization from ethanol and subsequent Kugelrohr distillation to provide a yield of 17.5 g (b.p. 195°-220° C. at 0.1 torr).
