Procedure

In DMF (20 ml) were suspended 1-(N-acetylglycyl)-7-[4-(2-butoxyethoxy)phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxylic acid (0.85 g), 4-[N-methyl-N-(tetrahydro-2H-pyran-4-yl)aminomethyl]aniline dihydrochloride (0.52 g) and 1-hydroxybenzotriazole (0.3 g). Under ice-cooling, to the suspension were added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (1 g), triethylamine (1.7 ml) and 4-dimethylaminopyridine (catalytic amount), and the mixture was stirred at room temperature overnight. The solvent was evaporated and, 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. The solvent was evaporated and the residue was purified with basic silica gel column chromatography (ethyl acetate/methanol/triethylamine) to give 1-(N-acetylglycyl)-7-[4-(2-butoxyethoxy)phenyl]-N-[4-[[N-methyl-N-(tetrahydro-2H-pyran-4-yl)amino]methyl]phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxamide (1.1 g) as pale yellow amorphous.
