Vorschrift

In a 10 mL sealed tube under N2 were dissolved CESIUM CARBONATE (221 mg, 677 μmol), 8-((6-phenyl-[1,2,4]triazolo[4,3-b]pyridazin-3-yl)methylamino)-1,5-naphthyridin-3-ol (50 mg, 135 μmol), 1-(2-chloroethyl)pyrrolidine hydrochloride (46 mg, 271 μmol) and SODIUM IODIDE (41 mg, 271 μmol) in 1 mL of DMSO then stirred and heated at 75° C. for 3 h. The reaction mixture was diluted with H2O and the aqueous phase was extracted 3× with DCM then the organic layer was dried over Na2SO4, filtered and concentrated under reduced pressure. The crude mixture was purified by MPLC (ISCO) with DCM/DCM:MeOH:NH4OH (90:10:1)100:0 to 90:10 to afforded N-((6-phenyl-[1,2,4]triazolo[4,3-b]pyridazin-3-yl)methyl)-7-(2-(pyrrolidin-1-yl)ethoxy)-1,5-naphthyridin-4-amine (7 mg, 11% yield) as a yellow solid. MS m/z=466.2 [M+1]+. Calc'd for C26H26N8O: 467.0.
