To a solution of thiazole III (2.0 g, 6.6 mmol) and the phenyl boronic acid (9.9 mmol) in THF (10 mL) was added potassium fluoride (1.15 g, 19.8 mmol), palladium (II) acetate (74 mg, 0.33 mmol), and 2-(di-t-butylphosphino)biphenyl (197 mg, 0.66 mmol). This mixture was stirred at 25° C. for 24 h. Diethyl ether (100 mL) was then added and the mixture was washed with 1 N aqueous NaOH (2×50 mL), saturated aqueous NaCl (1×50 mL), dried over MgSO4 and concentrated in vacuo to give an off-white solid. Purification by flash chromatography (silica, 0-2.5% ethyl acetate/hexane) gave the product, generally in 60-90% yield.
