实验步骤: To a mixture of the product from Step 1, -bromo-4-iodo-2-methoxybenzene (750 mg, 2.4 mmol), CsF (1.09 g, 7.2 mmol), (2-amino-4-cyanophenyl)boronic acid hydrochloride (390 mg, 2.4 mmol), and Pd(PPh3)4 (277 mg, 0.24 mmol) was added DME (15 mL) under nitrogen. It was then heated to 100° C. After 36 hours, EtOAc and water were added to the resulting thick red suspension. The organic layer was washed with brine, dried over Na2SO4, and the solvent was removed in vacuo. The residue was purified on silica (gradient elution, 3-50% EtOAc/hexanes) to yield the title compound as a red oil. LRMS (M+H)+=303.1.
