実験手順
In dimethylformamide (5 ml) was dissolved 7-(4-ethoxyphenyl)-1-methyl-2,3-dihydro-1-benzazepine-4-carboxylic acid hydrochloride (0.5 g), and to the mixture was added, under ice-cooling, thionyl chloride (0.25 ml). The mixture was stirred at room temperature for 45 minutes, and the solvent was evaporated. The residue was dissolved in tetrahydrofuran (15 ml), and the mixture was added dropwise to a suspension of 4-((N-(3-ethoxypropyl)-N-methylamino)methyl)aniline dihydrochloride (0.41 g) and triethylamine (1.2 ml) in tetrahydrofuran (10 ml), under ice-cooling. Under nitrogen atmosphere, the mixture was stirred at room temperature overnight, and the solvent was evaporated. To the residue was added water, and the mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated brine, and dried with anhydrous magnesium sulfate. Under reduced pressure, the solvent was evaporated, and the residue was purified with silica gel column (methanol/triethylamine/ethyl acetate) to give crude crystals, which were recrystallized from ethyl acetate-hexane to give N-(4-((N-(3-ethoxypropyl)-N-methylamino)methyl)phenyl)-7-(4-ethoxyphenyl)-1-methyl-2,3-dihydro-1-benzazepine-4-carboxamide (Compound 319) (0.39 g) as pale yellow crystals.
