Participants

Reaction Steps

7-[4-(2-butoxyethoxy)phenyl]-1-isobutyl-N-[2-[[(1-propylimidazol-5-yl)methyl]sulfanyl]benzimidazol-5-yl]-2,3-dihydro-1-benzazepine-4-carboxamide (0.64 g) was dissolved in methylene chloride (19.2 ml), and a solution of metachloroperbenzoic acid (0.27 g) in methylene chloride (12.8 ml) was added dropwise to the solution at −78° C. The mixture was stirred for 15 minutes, and to the mixture was added an aqueous solution of saturated sodium thiosulfate, and the mixture was allowed to be warmed to room temperature. The mixture was extracted with ethyl acetate, washed with saturated brine, and dried over magnesium sulfate. The solvent was removed under reduced pressure, and the obtained residue was purified by silica gel column chromatography, to give 7-[4-(2-butoxyethoxy)phenyl]-1-isobutyl-N-[2-[[(1-propylimidazol-5-yl)methyl]sulfinyl]benzimidazol-5-yl]-2,3-dihydro-1-benzazepine-4-carboxamide (Compound 313) (0.21 g).
