Participants

Reaction Steps

7-[4-(2-butoxyethoxy)phenyl]-N-[4-[[(1-oxido-2-pyridinyl)sulfonyl]methyl]phenyl]-1-(trifluoroacetyl)-2,3-dihydro-1-benzazepine-4-carboxamide (137 mg) was dissoved in ethanol (4.0 ml), sodium borohydride (36 mg) was added to the mixture, and the mixture was stirred at room temperature for 3 hours. Sodium borohydride (36 mg) was further added to the mixture, and the mixture was stirred at room temperature for 3 hours. The solvent was removed under reduced pressure and the obtained residue was added to water, and 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]-N-[4-[[(1-oxido-2-pyridinyl)sulfonyl]methyl]phenyl]-2,3-dihydro-1-benzazepine-4-carboxamide (Compound 202) (85 mg).
