The compound according to the invention is prepared analogously to Example 2 by Suzuki coupling of 5-butyl-2-[3-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]tetrahydropyran to 5-((4-bromo-2,6-difluorophenyl)difluoromethoxy)-1,3-difluoro-2-(trifluoromethyl)benzene. 5-Butyl-2-{4′-[(3,5-difluoro-4-trifluoromethylphenoxy)difluoromethyl]-2,3′,5′-trifluorobiphenyl-4-yl}tetrahydropyran is obtained as a colourless solid having an m.p. of 88° C. The successful synthesis is confirmed perfectly by NMR spectroscopy (1H, 19F, 13C) and mass spectroscopy (EI).
