Temperature: 100 °C

Procedure

To a mixture of 3-methyl-2-(methylsulfonyl)-3H-imidazo[4,5-b]pyridine (81 mg) and 1-ethyl-3-(4-hydroxyphenyl)-7-(trifluoromethyl)-1,3-dihydro-2H-imidazo[4,5-b]pyridin-2-one (103 mg) in DMF (dry) (1.5 ml) was added NaH (19.12 mg), and the mixture was stirred at 100° C. for 1 h. The mixture was heated at 180° C. for 30 min under microwave irradiation. The mixture was poured into water, and the mixture was extracted with EtOAc. The organic layer was separated, washed with brine, dried over Na2SO4 and concentrated in vacuo. The residue was purified by column chromatography (silica gel, EtOAc/hexane) to give the title compound as white crystals (62.2 mg).
