Versuchsvorschrift

A mixture of 7-fluoro-6-[6-(1H-pyrazol-4-yl)-imidazo[1,2-b]pyridazin-3-ylmethyl]-quinoline (Example 251, 50 mg, 0.145 mmol), 1-(2-chlorethyl)pyrrolidine hydrochloride (25 mg, 0.145 mmol) and Cs2CO3 (99 mg, 0.305 mmol) in DMF (1 mL) was stirred at 95° C. for 18 h. The mixture was diluted with EtOAc and washed with NaHCO3 and brine. The organic layer was dried over Na2SO4, filtered and concentrated. The residue was purified by flash chromatography (CombiFlash® Companion System®, with a 4 g RediSep® silica gel column, DCM/(DCM/MeOH 19:1)=100:0→0:100) to afford the title compound as a foam (tR 3.06 min (conditions 3), MH+=442.2, 1H-NMR in DMSO-d6: 8.84 (m, 1H); 8.44 (s, 1H); 8.34 (d, 1H); 8.08 (m, 2H); 8.03 (d, 1H); 7.76 (d, 1H); 7.61 (s, 1H); 7.52 (d, 1H); 7.46 (dd, 1H); 4.54 (s, 2H); 4.26 (t, 2H); 2.83 (m, 2H); 2.44 (m, 4H); 1.62 (m, 4H)).
