Procedure

To a solution of 7-[4-(2-butoxyethoxy)phenyl]-1-(3-ethoxypropyl)-2,3-dihydro-1H-1-benzazepine-4-carboxylic acid (250 mg) in THF (10 ml) were added thionyl chloride (0.078 ml) and DMF (one droplet) at room temperature, and the mixture was stirred for 1.5 hours. The solvent was evaporated under reduced pressure, and the resulting residue was dissolved in THF (20 ml), which was added dropwise to a solution of 4-[[N-methyl-N-(tetrahydropyran-4-yl)amino]methyl]aniline (128 mg) and triethylamine (0.44 ml) in THF (3 ml) at 0° C. The mixture was stirred at room temperature for 64 hours, water was added thereto, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, and dried with magnesium sulfate. After concentration under reduced pressure, the residue was purified with column chromatography (ethanol:ethyl acetate=1:4), and the resulting crystals were purified by recrystallization (hexane-ethyl acetate) to give 7-[4-(2-butoxyethoxy)phenyl]-1-(3-ethoxypropyl)-N-[4-[N-methyl-N-tetrahydropyran-4-yl)amino]methyl]phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxamide (Compound 106) (224 mg) as yellow crystals.
