実験手順

To a solution of 1-(3-methoxypropyl)-7-[4-(2-propoxyethoxy)phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxylic acid (250 mg) in THF (10 ml) were added thionyl chloride (0.083 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 (15 ml), which was added dropwise to a solution of 4-[[N-methyl-N-(tetrahydropyran-4-yl)amino]methyl]aniline (138 mg) and triethylamine (0.48 ml) in THF (3 ml) at 0° C. The mixture was stirred at room temperature for 3 hours, water was added thereto, and the mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated brine, and dried with magnesium sulfate. After concentration under reduced pressure, the residue was purified with column chromatography (ethanol:ethyl acetate=1:4→1:3→1:2), and the resulting crystals were purified by recrystallization (hexane-ethyl acetate) to give 1-(3-methoxypropyl)-N-[4-[[N-methyl-N-(tetrahydropyran-4-yl)amino]methyl]phenyl]-7-[4-(2-propoxyethoxy)phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxamide (Compound 103) (264 mg) as yellow crystals.
