7-(2-(2-(Nonafluorobutoxy) tetrafluoroethoxy)-2,2-difluoroethoxy)-1-bromoheptane → 5-Hexyloxy-2-[4-(7-(2-(2-(nonafluorobutoxy)tetrafluoroethoxy)-2,2-difluoroethoxy)heptyloxy)phenyl]pyrimidine

Participants

Reaction Steps

The title compound was prepared essentially as described in Example 1 by combining 5-hexyloxy-2-(4-hydroxyphenyl)pyrimidine (3.0 g, 11.0 mmol) and 7-(2-(2-(nonafluorobutoxy)tetrafluoroethoxy)-2,2-difluoroethoxy)-1-bromoheptane (7.7 g, 12.0 mmol; prepared by combining 1,7-dibromoheptane with 2-(2-(nonafluorobutoxy)tetrafluoroethoxy)-2,2-difluoroethanol). Product was isolated by addition of water (50 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. 210-222° C. at 0.03 torr; yield 7.3 g).
