Reaction Steps

The title compound was prepared essentially as in Example 1 by combining 6-(2-(2-(2-(trifluoromethoxy)tetrafluoroethoxy)tetrafluoroethoxy)-2,2-difluoroethoxy)-1-bromohexane (85 g, 0.155 mol; prepared from 1,6-dibromohexane (500 g, 0.7 mol), 2-(2-(2-(trifluoromethoxy)tetrafluoroethoxy)tetrafluoroethoxy)-2,2-difluoroethanol (150 g, 0.37 mol), and potassium t-butoxide (412 mL of 1M solution in t-butanol)) with 5-octyl-2-(4-hydroxyphenyl)pyrimidine (45 g, 0.162 mol). The crude product was further purified by recrystallization from heptane and subsequently dried in a vacuum oven (yield of 93.0 g).
