Reaction Steps

5-[3-(3-pyrazol-1-yl-phenyl)-imidazo-[1,2-a]-pyridin-7-yl]-nicotinonitrile (Ex. 1.8) (1 eq, 0.099 mmol, 40 mg) and potassium hydroxide (10 eq, 0.99 mmol, 64.8 mg) are dissolved in tBuOH (2 ml) and the reaction mixture is heated at 85° C. for 1.5 h. At the completion of this time the solvent is removed in vacuo and the reaction mixture is diluted with NaHCO3. The aqueous phase is extracted with EtOAc. The organic layer is washed with brine, dried over MgSO4, filtered and evaporated to dryness. The reaction mixture is purified by flash chromatography on silica eluting with DCM/MeOH 9/1 to yield 5-[3-(3-pyrazol-1-yl-phenyl)-imidazo-[1,2-a]pyridin-7-yl]-nicotinamide as a yellow solid; [M+H]+=381
