Procedure

To 7-[4-(2-butoxyethoxy)phenyl]-1-isobutyl-N-(4-hydroxyphenyl)-2,3-dihydro-1H-1-benzazepine-4-carboxamide (0.5 g), 2-chloromethyl-1-propylimidazole hydrochloride (0.22 g) and potassium carbonate (0.4 g), N,N-dimethylformamide (15 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/hexane) to give crude crystals, which were recrystallized from ethyl acetate-hexane, to give 7-[4-(2-butoxyethoxy)phenyl]-1-isobutyl-N-[4-[(1-propylimidazole-2-yl) methoxy]phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxamide (compound 25) (0.51 g) as pale yellow crystals.
