PROCEDURE

实验过程

To a mixture of 1-(2-ethyl-1-methyl-1H-benzimidazol-6-yl)-4-hydroxypyridin-2(1H)-one (500 mg), (5-chloro-2-thienyl)methanol (552 mg) and tributylphosphine (1.38 ml) in THF (10 ml) was added 1,1′-(azodicarbonyl)dipiperidine (1.41 g), and the mixture was stirred at 60° C. for 2 h. The reaction mixture was partitioned between EtOAc and water, and the organic layer was washed with brine, dried over MgSO4, and concentrated in vacuo. The residue was purified by NH silica gel column chromatography (hexane/EtOAc to MeOH/EtOAc). The resulting solid was recrystallized from EtOH to give the title compound (143 mg) as a white solid.
