Participants

Reaction Steps

7-[4-(2-butoxyethoxy)phenyl]-1-isobutyl-N-[6-[[(1-propylimidazol-5-yl)methyl]sulfanyl]-3-pyridinyl]-2,3-dihydro-1-benzazepine-4-carboxamide (1.4 g) was dissolved in methylene chloride (42 ml), and a solution of m-chloroperbenzoic acid (0.65 g) in methylene chloride (28 ml) was added dropwise to the solution at −78° C. The mixture was stirred for 15 minutes, and an aqueous solution of saturated sodium thiosulfate was added to the mixture. 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-[6-[[(1-propylimidazol-5-yl)methyl]sulfinyl]-3-pyridinyl]-2,3-dihydro-1-benzazepine-4-carboxamide (Compound 297) (0.41 g).
