Reaction Steps

The title compound was prepared essentially as in Example 1 by combining 3-(2-(2-(2-(trifluoromethoxy)tetrafluoroethoxy)tetrafluoroethoxy)-2,2-difluoroethoxy)propyl chloride (4.0 g, 8.4 mmol, Example 24) with 5-heptyl-2-(4-hydroxyphenyl)pyrimidine (2.3 g, 8.4 mmol). The resulting crude product was isolated essentially as described in Example 3 and purified by chromatography on silica gel, eluting with 10 vol. % ethyl acetate in hexane, followed by Kugelrohr distillation (215° C. at 0.3 torr) to provide a yield of 5 g.
