A mixture of N-[7-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3-isoquinolyl]cyclopropanecarboxamide (500 mg, 1.48 mmol), 1-bromo-2-fluoro-4-iodo-5-methyl-benzene (559 mg, 1.77 mmol), and bis(di-tert-butyl(4-dimethylaminophenyl)phosphine)dichloropalladium(II) (105 mg, 0.15 mmol) in ACN (6 mL) and saturated aqueous sodium carbonate (1 mL) was heated under microwave irradiation (Biotage) 120° C. for 20 minutes. The reaction mixture was diluted with ethyl acetate (50 mL) and washed with water (50 mL). The organic layer was separated, dried over sodium sulfate, filtered and concentrated in vacuo to provide a residue that was purified by flash chromatography (12 g, Silica, 0-60% ethyl acetate in heptane). Desired fractions were combined and evaporated in vacuo to afford the title compound as a white solid (385, 65%), which was used in the next step without further purification.
