(R)-4-[5-Bromo-6-(4-tert-butyl-cyclohexyloxy)-naphthalen-2-yl]-4-methyl-oxazolidin-2-one (0.2079 g, 0.0004516 mol), 4-trifluoromethoxy phenylboronic acid (0.130 g, 0.000632 mol), tetrakis(triphenylphosphine)palladium(0) (0.03 g, 0.00002 mol) and sodium carbonate (0.191 g, 0.00181 mol) were added to a capped 40 mL EPA vial equipped with a magnetic stir bar. The vial was degassed and purged with nitrogen. 1,2-Dimethoxyethane (5.00 mL, 0.0481 mol) was added and the mixture was stirred for 5 minutes. Water (3.00 mL, 0.166 mol) was then added and the mixture was heated at 95° C. After 3 h, HPLC analysis showed that the reaction was complete. Ethylacetate (5 mL) and water (5 mL) were added and the layers were separated. The combined organic phase was then dried over MgSO4, filtered, concentrated and purified by flash chromatography (0-55% EtOAc in hexane) to give 204.1 mg of the title compound (83% yield).
