실험 절차

To 4-[3-(2-Chloro-pyridin-4-yl)-3H-imidazo[4,5-b]pyridine-5-ylamino]-cyclohexanol (1 eq, 100 mg, 0.29 mmol), 3-furyl boronic acid (1.05 eq, 0.3 mmol, 34 mg), Na2CO3 (2 eq, 0.58 mmol, 62 mg) in EtOH (2 ml) and H2O (0.7 ml) under inert atmosphere of N2 is added tetakis(triphenylphosphine) palladium (0.1 eq, 0.029 mmol, 21 mg). The reaction is heated in using microwave radiation at 80° C. for 2 hours. The mixture is diluted with H2O (5 ml) and extracted with EtOAc. The combined organic portions are washed with brine, dried (MgSO4) and concentrated in vacuo. The residue is purified by flash chromatography on silica eluting with 0-2.5% MeOH in EtOAc to afford the title compound; [M+H]+ 375.
