Reaction Steps

3-[(S)-1-(6-Fluoro-1H-indazol-5-yl)-ethyl]-6-(1-methyl-1H-pyrazol-4-yl)-imidazo[1,2-b]pyridazine (Example 165, 23 mg, 0.065 mmol) was dissolved in DMF (0.374 mL) and cooled down to 0° C. under nitrogen conditions. NaH (3.82 mg, 0.095 mmol) was added and the RM was stirred at 0° C. for 30 min. Then methyliodide (10.84 mg, 0.076 mmol) was introduced. The RM was allowed to warm up to rt and stirred for 2.5 h, then it was quenched with water. It was extracted twice with EtOAc. The organics were joined and washed with brine, dried over Na2SO4. The solvent was removed and the residue was purified by preparative HPLC with acetonitrile and water (+0.1% TFA). The acetonitrile was removed and the aqueous solution was basified with 5% NaHCO3. It was extracted twice with EtOAc and then the organics were joined and washed with brine. It was dried over Na2SO4 and the solvent was removed. The residue was triturated with pentane and the precipitate was filtered off to afford the title compound as a white solid (tR 1.0 min (conditions 2), MH+=376, 1H-NMR in DMSO-d6: 8.30 (s, 1H); 8.06 (d, 1H); 7.94 (s, 2H); 7.67 (s, 1H); 7.59 (d, 1H); 7.54 (d, 1H); 7.46 (d, 1H); 4.95 (q, 1H); 3.95 (s, 3H); 3.88 (s, 3H); 1.77 (d, 3H)).
