実験手順

To a solution of (rac)-7-fluoro-6-[1-(6-{1-[2-(tetrahydro-pyran-2-yloxy)-ethyl]-1H-pyrazol-4-yl}-imidazo[1,2-b]pyridazin-3-yl)-ethyl]-quinoline (Stage 255.1, 49 mg, 0.101 mmol) in DCM (3 mL) stirred at rt was added a solution of HCl in dioxane (4 M, 0.252 mL). The RM was stirred 1 h at rt, during this time the product precipitated as an oil. The residue was taken in DCM and water, then neutralized with a solution of 10% NaHCO3 and extracted with DCM. The combined organic phase was dried over MgSO4 and concentrated under reduced pressure. The residue was purified by flash chromatography (CombiFlash® Companion System®, with RediSep® silica gel column, EtOAc/MeOH (1% NH3)=100:0->80:20) to afford the title compound as a white crystalline powder (tR 3.40 min (conditions 3), MH+=403.3, 1H-NMR in DMSO-d6: 8.81 (d, 1H), 8.35-8.28 (m, 2H); 8.05 (d, 1H); 7.95-7.88 (m, 2H), 7.76 (d, 1H); 7.72 (s, 1H); 7.49 (d, 1H); 7.46-7.40 (m, 1H); 5.03 (q, 1H); 4.92 (t, 1H); 4.15 (t, 2H); 3.72 (q, 2H); 2.83 (d, 3H)).
