Dimethylformamide → 7-[4-(2-butoxyethoxy)phenyl]-1-isobutyl-N-[4-[(4-isobutyl-4H-1,2,4-triazol-3-yl)methoxy]phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxamide

Participants

Reaction Steps

To 7-[4-(2-butoxyethoxy)phenyl]-1-isobutyl-N-(4-hydroxyphenyl)-2,3-dihydro-1H-1-benzazepine-4-carboxamide (0.3 g), 3-chloromethyl-4-isobutyl-4H-1,2,4-triazole hydrochloride (0.15 g) and potassium carbonate (0.4 g), N,N-dimethylformamide (5 ml) was added, and the mixture was stirred overnight under nitrogen atmosphere at room temperature. The mixture was poured into water, and the mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated brine, dried over anhydrous magnesium sulfate, and then, the solvent was distilled off. The residue was purified by silica gel column chromatography (elution solvent: ethyl acetate/methanol/triethylamine), to give 7-[4-(2-butoxyethoxy)phenyl]-1-isobutyl-N-[4-[(4-isobutyl-4H-1,2,4-triazol-3-yl)methoxy]phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxamide (compound 27) (0.31 g) as yellow amorphous.
