Reaction Steps

To a stirred suspension of NaH (40% oil dispersion, 50 mg) in THF (9 ml) was added a solution of 1-(2-cyclopropyl-1-methyl-1H-benzimidazol-6-yl)-4-hydroxypyridin-2(1H)-one (150 mg) in THF (1 ml) at 0° C., and then the mixture was stirred at room temperature for 30 min. 1-Bromomethyl-3-fluorobenzene (150 mg) in THF (0.5 ml) was added, and the resulting mixture was stirred at room temperature for 12 h. The reaction mixture was quenched with ice-water and extracted with DCM. The extract was washed with brine, dried over Na2SO4 and concentrated in vacuo. The crude product was purified by silica gel column chromatography (MeOH/DCM) followed by crystallization with DCM/hexane to give the title compound (49 mg) as a white solid.
