Reaction Steps
To a solution of 5-bromo-2-p-tolylbenzo[d]oxazole (146.1 mg, 0.50 mmol) in dioxane (1.5 mL) was added water (0.5 mL), 4-methoxyphenylboronic acid (114 mg, 0.75 mmol), potassium carbonate (138 mg, 1.00 mmol) and tetrakis(triphenylphosphine)palladium(0) (3 mg). The resulting suspension was heated in the microwave at 150° C. for 15 min. After cooling, the reaction was diluted with water and extracted with ethyl acetate. The combined organic layers were dried over anhydrous MgSO4 and evaporated. The resulting solid was purified by column chromatography eluting with ethyl acetate/hexanes 1:99 v/v to afford 60 mg (38%) of the title compound (LCMS RT=9.18 min, MH+ 316.1)
