الإجراء التجريبي

Tetrakis(triphenylphosphine)palladium(0) (6.4 mg, 5.5 μmol) was added to an N,N-dimethylformamide (1.0 ml) suspension of N-(3-bromo-6-cyano-4-iodo-2-methoxy-5-methylphenyl)-2,2-dimethylpropionamide (I-6) (50 mg, 111 μmol), trans-β-styreneboronic acid (17.2 mg, 116 μmol), potassium phosphate n-hydrate (74-78%, 64 mg, 222 μmol), followed by stirred overnight at 95° C. The reaction liquid was cooled, then ethyl acetate (30 ml) was added, followed by washing with saturated brine (30 ml×2), drying over anhydrous magnesium sulfate, concentrating under reduced pressure.
