실험 절차

3-Methyl-2-(methylsulfonyl)-3H-imidazo[4,5-b]pyridine (79 mg) was added to a solution of 1-cyclopropyl-3-(4-hydroxyphenyl)-1,3-dihydro-2H-imidazo[4,5-b]pyridin-2-one (100 mg) and NaH (17.96 mg) in DMF (2 mL) at 100° C. The mixture was heated at 180° C. for 1 h under microwave irradiation. The reaction mixture was diluted with MeOH and concentrated in vacuo. The residue was purified by column chromatography (NH silica gel, eluted with 0%-50% EtOAc in hexane) to give 1-cyclopropyl-3-{4-[(3-methyl-3H-imidazo[4,5-b]pyridin-2-yl)oxy]phenyl}-1,3-dihydro-2H-imidazo[4,5-b]pyridin-2-one (80 mg) as white crystals.
