Reaction Steps
To a solution of (4-(trifluoromethyl)thiophen-2-yl)methanol (50 mg) in THF (3 ml) were added 1-(2-ethyl-1-methyl-1H-benzo[d]imidazol-6-yl)-4-hydroxypyridin-2(1H)-one (73.9 mg), bis(2-methoxyethyl) azodicarboxylate (129 mg) and PPh3 (144 mg) at room temperature, and the mixture was stirred for 3 h. The mixture was poured into water and extracted with EtOAc. The organic layer was separated, washed with saturated NaHCO3 solution and brine successively, dried over MgSO4 and concentrated in vacuo. The residue was purified by column chromatography (EtOAc/MeOH) to give the title compound (10.2 mg) as white crystals.
