6-((6-phenyl-[1,2,4]triazolo[4,3-b]pyridazin-3-yl)methyl)quinolin-3-ol (0.05 g, 0.1 mmol) was dissolved in DMF (8 mL). SODIUM HYDRIDE (0.01 g, 0.3 mmol) was added and allowed to stir for 1 h at rt. 2-chloro-N,N-dimethylethanamine hydrochloride (0.06 g, 0.4 mmol), which was free-based using 5 N NaOH then extracted with ether, was added. The resulting mixture was continued to stir for 20 h at rt. Solvent was removed in vacuo. The crude material was purified using SiO2 chromatography (Teledyne Isco RediSep®, P/N 68-2203-026, 12 g SiO2, solvent system: DCM:MeOH(2M NH3)=95%:5%, Flow=30 mL/min) to afford the title compound MS m/z: 425.3 (M+H). Calc'd. for C25H24N6O—424.49.
