Versuchsvorschrift

6-(1-Methyl-1H-pyrazol-4-yl)-3-((S)-1-{1-[2-(tetrahydro-pyran-2-yloxy)-ethyl]-1H-indazol-5-yl}-ethyl)-imidazo[1,2-b]pyridazine (Example 195, 34 mg, 0.1 mmol) was added to a suspension of NaH (55%, 4.8 mg 0.11 mmol) in dry THF (0.5 mL) at 0° C. The RM was allowed to stir at rt for 15 min and 2-(2-bromo-ethoxy)-tetrahydro-pyran (0.024 mL, 0.150 mmol) was added at 0° C. It was stirred additionally 7 h at rt, then overnight at 60° C., and finally 7 h at 120° C. in a pressure safe capped vial. After cooling at rt the RM was taken-up in DCM, washed with brine, the 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=100:0->80:20) to afford 6-(1-methyl-1H-pyrazol-4-yl)-3-((S)-1-{2-[2-(tetrahydro-pyran-2-yloxy)-ethyl]-2H-indazol-5-yl}-ethyl)imidazo[1,2-b]pyridazine and the title compound (tR 4.05 min (conditions 2), MH+=472.3).
