Reaction Steps
To a solution of 1-(2-cyclopropyl-1-methyl-1H-benzimidazol-6-yl)-4-(hydroxymethyl)pyridin-2(1H)-one (150 mg), 4-fluorophenol (114 mg) and tributylphosphine (307 mg) in THF (5 ml) was added 1,1′-(azodicarbonyl)dipiperidine (385 mg), and the mixture was stirred at 60° C. for 4 h. The mixture was concentrated in vacuo, and diluted with DCM. The mixture was washed with water and brine successively, dried over Na2SO4, concentrated in vacuo and purified by column chromatography (MeOH/DCM) to afford the title compound (40 mg) as a white solid.
