실험 절차

In DMF (6 ml) was dissolved 1-butyl-7-[4-(2-propoxyethoxy)phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxylic acid (0.30 g). Under ice-cooling, to the mixture was added thionyl chloride (0.15 ml). The mixture was stirred at room temperature for 30 minutes. The solvent was evaporated under reduced pressure. In THF (20 ml) was suspended the residue, and the suspension was added dropwise to a solution of 4-[N-methyl-N-(tetrahydro-2H-pyran-4-yl)aminomethyl]aniline (0.17 g) and triethylamine (0.42 ml) in THF (5 ml), under ice-cooling. The mixture was stirred at room temperature overnight under nitrogen atmosphere. The solvent was evaporated under reduced solvent. Water was added to the mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated brine and dried with anhydrous magnesium sulfate. The solvent was evaporated, and the residue was purified with silica gel column chromatography (ethyl acetate/methanol/triethylamine). The material was dissolved in ethyl acetate-ethanol, and 6N hydrochloric acid was added to the solution. The solvent was evaporated. Diethyl ether was added to the residue, and the precipitates were filtered to give 1-butyl-7-[4-(2-propoxyethoxy)phenyl]-N-[4-[[N-methyl-N-(tetrahydro-2H-pyran-4-yl)amino]methyl]phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxamide dihydrochloride (Compound 30) (0.36 g) as pale yellow amorphous.
