実験手順
To a suspension of cerium chloride(III) (296 mg) in THF (4 ml) was added dropwise 1 M methylmagnesium bromide-THF solution (1.2 ml) at −78° C. After stirring for 10 min, a solution of 1-{2-[4-(9H-imidazo[1′,2′:1,2]imidazo[4,5-b]pyridin-9-yl)phenoxy]-1H-benzimidazol-1-yl}propan-2-one (338 mg) obtained in Example 10 in THF (20 ml) was added dropwise at −78° C., and the obtained mixture was warmed to room temperature. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was subjected to basic silica gel column chromatography (hexane/ethyl acetate), purified by HPLC (L-Column 2 ODS, 10 mM aqueous hydrogen carbonate ammonium-containing acetonitrile solution) and recrystallized from methanol/water to give the title compound (44.0 mg).
