Reaction Conditions

Reaction Steps

NaH (60% in oil, 51.5 mg) was added to a solution of (2-(perfluoroethyl)thiazol-4-yl)methanol (300 mg) in DMA (5 ml) at 0° C. After being stirred at 0° C. for 30 min, 4-bromo-1-(2-cyclopropyl-1-methyl-1H-benzo[d]imidazol-6-yl)pyridin-2(1H)-one (295 mg) was added to the reaction mixture. The mixture was stirred at 120° C. under N2 atmosphere for 1 h. The mixture was quenched with water and extracted with EtOAc. The organic layer was separated, washed with water and brine successively, dried over MgSO4 and concentrated in vacuo. The residue was purified by NH silica gel column chromatography (hexane/EtOAc), followed by crystallization from EtOH-water to give the title compound (25 mg) as a white solid.
