Reaction Steps

To a solution of 1-(2-cyclopropyl-1-methyl-1H-benzimidazol-6-yl)-4-hydroxypyridin-2(1H)-one (100 mg), (4-methoxy-phenyl)-methanol (98 mg) and tributylphosphine (320 μl) in THF (10 ml) was added 1,1′-(azodicarbonyl)dipiperidine (269 mg). The mixture was stirred under sonication at 50° C. for 1 h. The reaction mixture was then cooled to room temperature, and concentrated in vacuo. The crude residue was diluted with DCM (100 ml), and the DCM layer was washed with water (50 ml) and brine (30 ml), dried over Na2SO4 and concentrated in vacuo. The residue was purified by silica gel column chromatography (MeOH/DCM) to give the title compound (45 mg) as an off-white solid.
