Sodium Thiosulfate → HCID 69522093, compound

Participants

Reaction Steps

A solution of 7-[4-(2-butoxyethoxy)phenyl]-1-isobutyl-N-[4-[[(6-methyl-2-pyridinyl)methyl]sulfanyl]phenyl]-2,3-dihydro-1-benzazepine-4-carboxamide (0.39 g) in methylene chloride (7.8 ml) was added dropwise to a solution of m-chloroperbenzoic acid (0.21 g) in methylene chloride (7.8 ml) at −40° C., and the mixture was stirred for 20 minutes. To the reaction mixture was added an aqueous solution of saturated sodium thiosulfate, and the mixture was extracted with ethyl acetate. The organic layer was 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-[4-[[(6-methyl-2-pyridinyl)methyl]sulfinyl]phenyl]-2,3-dihydro-1-benzazepine-4-carboxamide (Compound 218) (146 mg).
