실험 절차

One droplet of DMF was added to a solution of 7-(4-propoxyethoxyphenyl)-1-(2-thienylmethyl)-2,3-dihydro-1-benzazepine-4-carboxylic acid (240 mg) in tetrahydrofuran (10 ml). Then, thionyl chloride (184 mg) was added at 0° C., the temperature was returned to room temperature, and the mixture was stirred under nitrogen atmosphere for 1 hour. The solvent and excess thionyl chloride were evaporated under reduced pressure, the resulting residue was suspended in tetrahydrofuran (30 ml), and the suspension was added to a solution of 4-[[N-methyl-N-(tetrahydropyran-4-yl)amino]methyl]aniline (137 mg) and triethylamine (629 mg) in tetrahydrofuran (10 ml) at 0° C. The suspension was stirred under nitrogen atmosphere at room temperature overnight, to the mixture was added water, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine and dried with magnesium sulfate. The solvent was evaporated under reduced pressure, the resulting residue was separated and purified with silica gel column chromatography (methanol:ethyl acetate=1:8), which was recrystallized from hexane-ethyl acetate to give N-[4-[[N-methyl-N-(tetrahydropyran-4-yl)amino]methyl]phenyl]-7-(4-propoxyethoxyphenyl)-1-(2-thienylmethyl)-2,3-dihydro-1-benzazepine-4-carboxamide (Compound 59) (152 mg) as yellow crystals.
