5-Bromo-3-(pyrimidin-2-ylmethoxy)benzo[d]isoxazole (120 mg, 0.39 mmol), 4-(trifluoromethoxy)phenylboronic acid (120 mg, 0.58 mmol), potassium carbonate (500 mg), and [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II) (25 mg, 0.034 mmol) were combined in 6 mL DMF. 3 mL water was added and the mixture was stirred at 80° C. for two hours. The reaction mixture was diluted with 60 mL ethyl acetate, washed with water and brine and evaporated under vacuum. Flash chromatographic purification on 12 g silica gel with 0-60% ethyl acetate in hexane gave 3-(pyrimidin-2-ylmethoxy)-5-(4-(trifluoromethoxy)phenyl)benzo[d]isoxazole (94 mg, 0.24 mmol).
