Vorschrift

6-(6-Chloro-imidazo[1,2-b]pyridazin-3-ylmethyl)-quinoline (Example 14, 70 mg, 0.237 mmol), KF (70 mg, 1.187 mmol) and sec-butylamine (484 μL, 4.75 mmol) were suspended in NMP (1 mL). The RM was stirred at 180° C. for 29 h. The mixture was diluted with EtOAc and washed with 1 M Na2CO3 (×1) and water (×2). The aqueous was further extracted with EtOAc (2×). The combined organic layer was dried over Na2SO4, filtered and concentrated. The residue was purified by flash chromatography (Flashmaster) and then crystallized in Et2O to afford the title compound as a beige solid (tR 4.28 min (conditions 4), MH+ 332.3, 1H-NMR in DMSO-d6: 8.83 (m, 1H); 8.25 (m, 1H); 7.92 (d, 1H); 7.83 (m, 1H); 7.70 (m, 1H); 7.61 (d, 1H); 7.48 (dd, 1H); 7.32 (s, 1H); 6.66 (d, 1H); 6.56 (d, 1H); 4.34 (s, 2H); 3.70 (m, 1H); 1.46 (m, 2H); 1.07 (d, 3H); 0.80 (t, 3H)).
