Reaction Steps

The title compound was prepared essentially as in Example 1 by combining 5-(2-(2-(2-(trifluoromethoxy)tetrafluoroethoxy)tetrafluoroethoxy)-2,2-difluoroethoxy)1-bromopentane (18.3 g, 38.5 mmol; prepared from 1,5-dibromopentane (107 g, 0.7 mol) and 2-(2-(2-(trifluoromethoxy)tetrafluoroethoxy)tetrafluoroethoxy)-2,2-difluoroethanol (125 g, 0.31 mol) essentially as in Example 2 ) with 5-octyl-2-(4-hydroxyphenyl)pyrimidine (10 g, 35 mmol) to provide product boiling at 200°-210° C. at 0.4 torr (yield of 20.8 g).
