Into a 8 mL sealed tube, was placed potassium fluoride (300 mg, 5.17 mmol, 6.00 equiv, 100%), copper(I) iodide (900 mg, 4.66 mmol, 5.50 equiv, 100%), trimethyl(trifluoromethyl)silane (720 mg, 5.07 mmol, 5.00 equiv, 100%), NMP (3 mL, 100%) and a solution of 1-chloro-7-iodoisoquinoline (as prepared in the previous step, 250 mg, 0.86 mmol, 1.00 equiv, 100%) in NMP (1 mL). The reaction mixture was stirred for 12 h at 120° C. in an oil bath. The resulting mixture was diluted with 20 mL of ethyl acetate, washed with 3×10 mL of saturated solution of KI, dried over anhydrous sodium sulfate, and concentrated under vacuum. The residue was purified by chromatography over a silica gel column with ethyl acetate:petroleum ether (1:50). The title compound was obtained as a yellow solid.
