Reaction Steps

To a solution of 7-[4-(2-butoxyethoxy)phenyl]-N-[4-[hydroxy(5-chloro-1-oxidopyridin-2-yl)methyl]phenyl]-1-trifluoroacetyl-2,3-dihydro-1H-1-benzazepine-4-carboxamide (0.20 g) in ethanol (30 ml), sodium borohydride (50 mg) was added at room temperature and the mixture was stirred for 2.5 hours. To the reaction solution was added sodium borohydride (50 mg), and the mixture was stirred for 2.5 hours. Sodium borohydride (50 mg) was further added to the mixture and the mixture was stirred for 1 hour. Sodium borohydride (50 mg) was further added to the mixture, and the mixture was stirred for 13 hours. Water was added to the mixture and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over magnesium sulfate and concentrated under reduced pressure. The obtained residue was separated and purified by column chromatography (ethyl acetate:hexane 4:1→ethyl acetate) to give 7-[4-(2-butoxyethoxy)phenyl]-N-[4-[hydroxy(5-chloro-1-oxidopyridin-2-yl)methyl]phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxamide (Compound 109) (53 mg) as yellow amorphous.
