Reaction Steps

5-Bromo-3-(pyrimidin-2-ylmethoxy)benzo[d]isoxazole (114 mg, 0.40 mmol), 4-(trifluoromethoxy)phenylboronic acid (100 mg, 0.49 mmol), potassium carbonate (500 mg), and [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II) (25 mg, 0.034 mmol) were combined in 3 mL DMF. 1.5 mL water was added and the mixture was stirred at 60° C. for 30 minutes. 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 the title compound (115 mg, 0.31 mmol).
