2.00 g (7.44 mmol) of 2-fluoro-6-octyloxypyridine-3-boronic acid, 1.64 g (5.72 mmol) of 1-bromo-4-octyloxybenzene, 0.26 g (0.22 mmol) of tetrakis(triphenylphosphine)palladium(0) and 11.16 ml (22.32 mmol) of 2-molar sodium carbonate solution are refluxed in 20 ml of benzene and 10 ml of ethanol for 6 hours. After distributing the reaction mixture between water and diethyl ether, the organic phase is washed with water, dried over sodium sulfate, filtered and concentrated. Purification of the residue by chromatography (silica gel, 95:5 hexane/ethyl acetate) and recrystallization from acetonitrile give 1.02 g of 2-fluoro-6-octyloxy3-(4-octyloxyphenyl)pyridine. ##STR23##
