Procedure

To a solution of 7-[4-(2-butoxyethoxy)phenyl]-1-trifluoroacetyl-2,3-dihydro-1H-1-benzazepine-4-carboxylic acid (0.5 g) and 1-hydroxybenzotriazole (0.28 g) in DMF (10 ml), was added 1-ethyl-3-(3′-dimethylaminopropyl)carbodiimide hydrochloride (0.40 g) at room temperature, and the mixture was stirred for 1 hour. To the reaction solution were added a solution of (4-aminophenyl)(3-methylpyridin-2-yl)methanol (0.27 g) and triethylamine (0.60 ml) in DMF (5 ml) and 4-dimethylaminopyridine (1 flake), and the mixture was stirred for 3 days. To the reaction solution was added water, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over magnesium sulfate and concentrated under reduced pressure. The obtained residue was separated and purified by column chromatography (ethyl acetate:hexane 1:3→1:2→1:1) to give 7-[4-(2-butoxyethoxy)phenyl]-N-[4-[hydroxy(3-methylpyridin-2-yl)methyl]phenyl]-1-trifluoroacetyl-2,3-dihydro-1H-1-benzazepine-4-carboxamide (Compound 99) (319.2 mg) as colorless amorphous.
