Reaction Steps

3-[3-(2-Furan-3-yl-pyridin-4-yl)-imidazo[1,2-b]pyridazin-7-yl]-benzoic acid ethyl ester (Ex. 41) (1 eq, 0.122 mmol, 50 mg) is dissolved in DCM (1 ml) and the reaction mixture is cooled to −70° C. DIBAL-H (1.5 M in THF, 10 eq, 1.22 mmol, 1.74 ml) is then added and the reaction is stirred at this temperature for 3 h. The reaction mixture is then poured in NaHCO3/EtOAc. The organic phase is separated and the aqueous phase is extracted with EtOAc. The combined organic phases are washed with brine, dried over MgSO4, filtered and the solvent is removed in vacuo. The reaction mixture is purified by flash column chromatography eluting with 9:1 DCM/MeOH to afford {3-[3-(2-Furan-3-yl-pyridin-4-yl)-imidazo[1,2-b]pyridazin-7-yl]-phenyl}-methanol as a light brown solid; [M+H]+=369
