7-[4-(2-butoxyethoxy)phenyl]-1-propyl-2,3-dihydro-1-benzazepine-4-carboxylic acid (1.0 g) was dissolved in THF (20 ml), DMF (2 droplets) was added to the solution, thionyl chloride (0.34 ml) was added to the solution, and the solution was stirred at room temperature for 1 hour. The solution was added dropwise to the solution of 4-[(2-pyridinylsulfanyl)methyl]aniline (0.56 g) and triethylamine (1.97 ml) in THF (20 ml) under ice-cooling at room temperature and the mixture was stirred for 2 hours. The reaction solution was added to water, and extracted with ethyl acetate. The organic layer was washed with saturated brine, and dried over magnesium sulfate. The solvent was removed under reduced pressure, and the obtained residue was purified by silica gel column chromatography, to give 7-[4-(2-butoxyethoxy)phenyl]-1-propyl-N-[4-[(2-pyridinylsulfanyl)methyl]phenyl]-2,3-dihydro-1-benzazepine-4-carboxamide (Compound 180) (0.56 g).
