Reaction Steps

A degassed mixture of 7-hydroxy-6-(6-(methyl(2,2,6,6-tetramethylpiperidin-4-yl)amino)pyridazin-3-yl)naphthalen-2-yl trifluoromethanesulfonate (21 mg, 0.033 mmol), zinc cyanide (5.00 mg, 0.043 mmol) and tetrakis(triphenylphosphine)palladium(0) (1.8 mg, 1.6 μmol) in DMF (0.8 mL) was heated at 120° C. under microwave irradiation for 1 h. The reaction mixture was filtered through celite, washed with EtOAc and concentrated. The residue was loaded on a 1 g SCX column, washed with MeOH, and eluted with 2 M NH3 in MeOH. The product-containing fractions were concentrated. The crude product was purified via HPLC to give the title compound as a light yellow solid (6.9 mg, 50% yield). LCMS Rt=0.55 min [Method Q], MS (M+1)=416.3. 1H NMR (METHANOL-d4) δ 8.26 (s, 1H), 8.16 (d, J=9.6 Hz, 1H), 8.04 (s, 1H), 7.86 (d, J=8.6 Hz, 1H), 7.32 (dd, J=8.6, 1.5 Hz, 1H), 7.27 (s, 1H), 7.22 (d, J=9.6 Hz, 1H), 5.05 (t, J=11.9 Hz, 1H), 2.94 (s, 3H), 1.61 (dd, J=13.1, 3.5 Hz, 2H), 1.49 (t, J=12.4 Hz, 2H), 1.30 (s, 6H), 1.14 (s, 6H).
