실험 절차

To a solution of 7-[4-(2-butoxyethoxy)phenyl]-1-isobutyl-2,3-dihydro-1H-1-benzazepine-4-carboxylic acid (252 mg) in tetrahydrofuran (10 ml) was added one droplet of DMF. Then, thionyl chloride (0.055 ml) was added to the mixture, and the mixture was stirred for 1 hour under nitrogen atmosphere. This solution was slowly added dropwise to a solution of 6-amino-1-methyl-2-(((1-propylimidazol-5-yl)methyl)sulfanyl)benzimidazole (158 mg) in pyridine (10 ml) at 0° C. under nitrogen atmosphere. The mixture was stirred overnight at room temperature under nitrogen atmosphere, water was added to the mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated brine, and dried over magnesium sulfate. The solvent was distilled off under reduced pressure and the obtained residue was purified by basic silica gel column chromatography (hexane:ethyl acetate=1:2→ethyl acetate), to give 7-[4-(2-butoxyethoxy)phenyl]-1-isobutyl-N-[1-methyl-2-(((1-propylimidazol-5-yl)methyl)sulfanyl)benzimidazol-6-yl]-2,3-dihydro-1H-1-benzazepine-4-carboxamide (319 mg) (Compound 446) as yellow amorphous.
