실험 절차

To a solution of 4-(5-methyl-9H-imidazo[1′,2′:1,2]imidazo[4,5-b]pyridin-9-yl)phenol (370 mg) obtained in Example 15, step E) in DMA (3 ml) was added potassium tert-butoxide (168 mg) at room temperature. After stirring for 10 min, a solution of 3-(2-methoxyethyl)-2-(methylsulfonyl)-3H-imidazo[4,5-b]pyridine (383 mg) in DMA (3 ml) was added, and the obtained mixture was stirred at 150° C. for 1 hr. 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 (hexane/THF) and recrystallized from acetone to give the title compound (531 mg).
