Procedure

In DMF (25 ml) were suspended 7-[4-(2-butoxyethoxy)phenyl]-1-(N,N-dimethyl-4-sulfamoylphenyl)-2,3-dihydro-1H-1-benzazepine-4-carboxylic acid (0.3 g), 4-[N-methyl-N-(tetrahydro-2H-pyran-4-yl)aminomethyl]aniline dihydrochloride (0.19 g) and 1-hydroxybenzotriazole (0.07 g). Under ice-cooling, to the suspension were added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.15 g), triethylamine (0.37 ml) and 4-dimethylaminopyridine (catalytic amount), and the mixture was stirred at room temperature overnight. The solvent was evaporated, water was added to the residue, and the mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated brine, and dried with anhydrous magnesium sulfate, and the solvent was evaporated. The residue was purified with silica gel column (ethyl acetate/methanol/triethylamine) to give crude crystals, which were recrystallized from ethyl acetate-hexane to give 7-[4-(2-butoxyethoxy)phenyl]-1-(N,N-dimethyl-4-sulfamoylphenyl)-N-[4-[[N-methyl-N-(tetrahydro-2H-pyran-4-yl)amino]methyl]phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxamide (Compound 47) (0.12 g) as colorless crystals.
