9-bromo-4-iodo-6-[(1,2,2-trimethylpropyl)amino]benzo[c]-1,6-naphthyridin-1(2H)-one (50 mg, 0.100 mmol), palladium(II) chloride (0.355 mg, 1.999 μmol), (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (1.157 mg, 1.999 μmol), triethylamine (18.11 μl, 0.130 mmol) and 1-butanol (1000 μl) were combined in a 40 mL vial and sparged with nitrogen for 5 minutes. The cap on the vial was removed and the atmosphere changed to carbon monoxide by pressurizing to 30 psi and releasing the pressure 3 times inside a stainless steel pressure vessel. Then, the pressure of CO was adjusted to 100 psi and heated to 100° C. for 5 h. Then, the reaction was cooled to room temperature, the reaction was then poured into ethyl acetate, washed with saturated NaHCO3, brine, dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The residue was purified by preparative HPLC Reverse phase (C-18), eluting with Acetonitrile/Water+0.05% TFA, to afford the title compound as a white solid. 1H NMR (500 MHz, C2D6SO) δ 11.68 (d, 1H, J=6.0 Hz), 10.04 (d, 1H, J=2.0 Hz), 8.50 (d, 1H, J=9.0 Hz), 7.83 (d, 1H, J=7.0 Hz), 7.78 (d, 1H, J=7.5 Hz), 7.68 (d, 1H, J=8.5 Hz), 4.81 (m, 1H), 4.22 (m, 2H), 1.68 (m, 2H), 1.37 (m, 2H), 1.17 (m, 6H), 0.93 (s, 9H). LRMS (ESI) calc'd for (C23H29BrN3O3) [M+H]+ 476.1; found 476.1.
