Reaction Steps

In a glass tube were placed 2-chloro-oxazole-4-carboxylic acid [1-(3,5-difluoro-4-methanesulfonylamino-phenyl)-ethyl]-amide (100 mg, 0.26 mmol), 3-trifluoromethyl phenyl boronic acid (60 mg, 0.32 mmol), 2N—Na2CO3 (0.5 mL), Pd(PPh3)4 (4.6 mg, 0.004 mmol), toluene (1.0 mL), ethanol (0.5 mL), and a magnetic stir bar. The mixture was stirred overnight at 110° C. and was diluted with EtOAc and water. The organic layer was washed with saturated ammonium chloride, water and brine, dried over anhydrous magnesium sulfate, filtered, and concentrated under reduced pressure. The crude residue was purified by column chromatography (gradient 12% to 100% EtOAc in n-hexane) to give title compound (30 mg, 29%).
