HCID 695218227-[4-(2-butoxyethoxy)phenyl]-N-[4-[hydroxy(1-oxidopyridin-2-yl)methyl]-3-trifluoromethylphenyl]-1-propyl-2,3-dihydro-1H-1-benzazepine-4-carboxamide

Procedure

7-[4-(2-butoxyethoxy)phenyl]-N-[4-[hydroxy(1-oxidopyridin-2-yl)methyl]-3-trifluoromethylphenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxamide (0.53 g) and propionyl aldehyde (0.3 ml) were dissolved in 1,2-dichloroethane (50 ml), and to the solution, triacetoxy sodium borohydride (0.87 g) was added under ice-cooling and the mixture was stirred overnight at room temperature. The mixture was neutralized with solution of sodium bicarbonate, concentrated, and extracted with ethyl acetate. The organic layer was washed with water and saturated brine, and dried over anhydrous magnesium sulfate. The solvent was distilled off, and the residue was purified by silica gel column chromatography (elution solvent: ethyl acetate/methanol/triethylamine), to give 7-[4-(2-butoxyethoxy)phenyl]-N-[4-[hydroxy(1-oxidopyridin-2-yl)methyl]-3-trifluoromethylphenyl]-1-propyl-2,3-dihydro-1H-1-benzazepine-4-carboxamide (compound 13) (0.46 g) as yellow amorphous.
