Procedure

To a solution of 4-chloro-1-(2-cyclopropyl-1-methyl-1H-benzimidazol-6-yl)pyridin-2(1H)-one (150 mg) and (5-bromo-2-furyl)methanol (177 mg) in toluene (2.0 ml) was added potassium tert-butoxide (112 mg) at 100° C., and the mixture was stirred for 30 min. The mixture was quenched with water (2 ml), and the precipitate was collected. The resulting solid was recrystallized from EtOH—H2O to give the title compound (158 mg) as an off-white solid.
