Procedure

To a solution of 7-[4-(2-butoxyethoxy)phenyl]-1-formyl-2,3-dihydro-1H-1-benzazepine-4-carboxylic acid (280 mg) and 1-hydroxybenzotriazole (0.14 g) in DMF (10 ml), 1-ethyl-3-(3′-dimethylaminopropyl)carbodiimide hydrochloride (0.20 g) was added at room temperature, and the mixture was stirred for 0.5 hour. To the reaction solution, a solution of (R)-(4-aminophenyl)-(2-pyridyl) methanol (150 mg) and triethylamine (0.28 ml) in DMF (10 ml) was added dropwise. The mixture was stirred for 3 days at room temperature, water was added to the mixture and the mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated brine, dried over magnesium sulfate and concentrated under reduced pressure. The obtained residue was separated and purified with column chromatography (ethyl acetate) and recrystallized from ethyl acetate-diisopropylether to give 7-[4-(2-butoxyethoxy)phenyl]-1-formyl-N-[4-[(R)-hydroxy(2-pyridyl)methyl]phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxamide (Compound 76) (154.5 mg) as pale yellow crystals.
