Reaction Steps

[2-(Chloromethoxy)ethyl](trimethyl)silane (1.673 mL) was added to a solution of 3-[4-(benzyloxy)phenyl]-1,3-dihydro-2H-imidazo[4,5-b]pyridin-2-one (2.0 g) and sodium hydride (0.504 g) (60% in mineral oil) in DMF (5.0 mL) at 0° C. The mixture was stirred at room temperature under a dry atmosphere (CaCl2 tube) for 1 h. After the reaction, the reaction mixture was diluted with MeOH and concentrated in vacuo. The residue was purified by column chromatography (silica gel, eluted with 0%-100% EtOAc in hexane) to give 3-[4-(benzyloxy)phenyl]-1-{[2-(trimethylsilyl)ethoxy]methyl}-1,3-dihydro-2H-imidazo[4,5-b]pyridin-2-one (2.75 g) as a white solid.
