Procedure
7-[4-(2-butoxyethoxy)phenyl]-1-trifluoroacetyl-2,3-dihydro-1H-1-benzazepine-4-carboxylic acid (2 g), (4-amino-2-trifluoromethylphenyl)(4-methylpyridin-2-yl)methanol (1.2 g) and 1-hydroxybenzotriazole (0.96 g) were dissolved in N,N-dimethylformamide (25 ml), and to the solution were added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (2.4 g), triethylamine (3 ml) and 4-dimethylaminopyridine (catalytic amount) at room temperature under ice-cooling, and the mixture was stirred overnight. The mixture was poured into water, and the mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated brine, and dried over anhydrous magnesium sulfate, and then, the solvent was distilled off. The residue was purified by basic silica gel column chromatography (elution solvent: ethyl acetate/hexane), to give 7-[4-(2-butoxyethoxy)phenyl]-N-[4-[hydroxy(4-methylpyridin-2-yl)methyl]-3-trifluoromethylphenyl]-1-trifluoroacetyl-2,3-dihydro-1H-1-benzazepine-4-carboxamide (1.2 g) as pale yellow amorphous.
