Reaction Steps

To a mixture of 1-(2-cyclopropyl-1-methyl-1H-benzimidazol-6-yl)-4-hydroxypyridin-2(1H)-one (100 mg), (2,5-dichloro-3-thienyl)methanol (130 mg), tributylphosphine (0.264 ml) and THF (10 ml) was added 1,1′-(azodicarbonyl)dipiperidine (269 mg), and the mixture was stirred at 60° C. for 2 h. The reaction mixture was diluted with EtOAc, washed with water and brine successively, dried over MgSO4, and concentrated in vacuo. The residue was purified by NH silica gel column chromatography (hexane/EtOAc), followed by silica gel column chromatography (hexane/EtOAc then EtOAc/MeOH) to give the title compound (39.9 mg) as an off-white solid.
