실험 절차

7-Fluoro-6-[6-(1-piperidin-4-yl-1H-pyrazol-4-yl)-imidazo[1,2-b]pyridazin-3-ylmethyl]-quinoline (Example 180, 50 mg, 0.117 mmol) and triethylamine (33 μL, 0.234 mmol) were dissolved in THF (1 mL). Acetyl chloride (9 mg, 0.117 mmol) was then added dropwise and the mixture was stirred at rt for 2 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 9:1+NH3)=100:0→0:100) to afford the title compound as a foam (tR 3.50 min (conditions 3), MH+=470.2, 1H-NMR in DMSO-d6: 8.84 (m, 1H); 8.51 (s, 1H); 8.34 (m, 1H); 8.09 (m, 2H); 8.04 (d, 1H); 7.76 (d, 1H); 7.60 (s, 1H); 7.53 (d, 1H); 7.47 (dd, 1H); 4.55 (s, 2H); 4.48 (m, 2H); 3.92 (m, 1H); 3.21 (m, 1H); 2.72 (m, 1H); 2.04 (m, 5H); 1.89 (m, 1H); 1.75 (m, 1H)).
