실험 절차

To a solution of 4-(9H-imidazo[1′,2′:1,2]imidazo[4,5-b]pyridin-9-yl)phenol (175 mg) obtained in Example 9, step C) in DMF (2 ml) was added sodium hydride (60% in oil, 32 mg) at room temperature by small portions. After stirring for 10 min, a solution of 3-methyl-2-(methylsulfonyl)-3H-imidazo[4,5-b]pyridine (169 mg) in DMF (1.5 ml) was added, and the obtained mixture was stirred under microwave irradiation at 180° C. for 30 min. The reaction mixture was poured into water, and the mixture was extracted with ethyl acetate. The extract was washed with water and saturated brine, dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by basic silica gel column chromatography (THF) and recrystallized from methanol/water to give the title compound (179 mg).
