Reaction Steps

To a suspension of 4-bromo-2-(trifluoromethyl)phenol (8.00 g) in 1,4-dioxane (100 ml), triphenylphosphine (10.99 g) and 4-pyridylcarbinol (3.84 g) were added. Then diisopropyl azodicarboxylate (8.93 g) was dropwised and stirred at 20° C. for 18 h. The mixture was evaporated off the solvent, diethyl ether (100 ml) and iso-hexane (25 ml) were added and stirred at 20° C. for 2 h, stood for 3 days, filtered and washed with diethyl ether and iso-hexane. The filtrate was concentrated and purified by Biotage SNAP cartridge KP-Sil column (100 g, heptane:ethyl acetate=1:0, 2:1 to 1:1) to give 11.16 g red-orange oil as 4-((4-bromo-2-(trifluoromethyl)phenoxy)methyl)-pyridine (80% purity).
