Reaction Steps
To a mixture of 4-hydroxy-1-(2-((1RS,2SR)-2-(2-hydroxypropan-2-yl)cyclopropyl)-1-methyl-1H-benzimidazol-6-yl)pyridin-2(1H)-one (100 mg), (5-chloro-3-thienyl)methanol (77 mg), tributylphosphine (0.219 ml) and THF (10 ml) was added 1,1′-(azodicarbonyl)dipiperidine (223 mg), and the mixture was stirred at 60° C. for 2 h. The solvent was evaporated, and the residue was purified by column chromatography (hexane/EtOAc then EtOAc/MeOH). The resulting solid was suspended in toluene, and the insoluble material was collected by filtration to give the title compound (12 mg) as an off-white solid.
