Sodium Thiosulfate → HCID 178423662, compound

Participants

Reaction Steps

To a suspension of N-[4—(2-pyridyl)phenyl]-7—(4-methylphenyl)-2,3-dihydro-1-benzoxepine-4-carboxamide (400 mg) in dichloromethane (10 ml) was added 3-chloroperbenzoic acid (70%, 0.25 g) at 0° C., and the mixture was stirred at room temperature for 70 hours. To the mixture was added sodium thiosulfate solution, and the mixture was stirred for minutes. The mixture was extracted with dichloromethane. The organic layer was washed with saturated sodium bicarbonate solution and saturated sodium chloride solution, and dried with magnesium sulfate. The mixture was concentrated, purified with column chromatography (ethanol/ethyl acetate=1:1) to give crystals, which were dissolved in chloroform. The mixture was concentrated, and to the residue was added ethanol. Precipitated crystal was collected by filtration to give crystals, which were washed with ethanol to give N-[4—(1-oxidopyridin-2-yl)phenyl]-7—(4-methylphenyl)-2,3-dihydro-1-benzoxepine-4-carboxamide (Compound 160) (60 mg) as colorless crystals.
