실험 절차

To a mixture of 4-(3-ethyl-1H-pyrazolo[3,4-b]pyridin-1-yl)phenol (120 mg), sodium hydride (60% in oil, 21.0 mg) and DMF (5.0 ml) was added 2-chloro-1-methyl-1H-benzimidazole (84 mg), and the mixture was stirred under microwave irradiation at 180° C. for 1 hr. The reaction mixture was diluted with methanol, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate) to give the title compound (100 mg).
