实验过程

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 mixture, and thionyl chloride (0.34 ml) was added to the mixture. The mixture was stirred at room temperature for 1 hour, and the mixture was added dropwise to the solution of 4-(2-pyridinylsulfanyl) aniline (0.53 g) and triethylamine (1.97 ml) in THF (20 ml) under ice-cooling, and the mixture was stirred at room temperature for 2 hours. The reaction solution was added to water, and extracted with ethyl acetate. The organic layer 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)phenyl]-2,3-dihydro-1-benzazepine-4-carboxamide (Compound 182) (0.57 g).
