In phosphorus oxychloride (25 ml) was dissolved 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 (0.5 g). The solution was heated to stir at room temperature for 7 hours and at 50° C. for 2 hours, and the solvent was evaporated. To the residue was added sodium hydrogen carbonate solution, 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/hexane). The resulting crude crystals were recrystallized from ethyl acetate-hexane to give 7-[4-(2-butoxyethoxy)phenyl]-1-(2-methyloxazol-5-yl)-N-[4-[[N-methyl-N-(tetrahydro-2H-pyran-4-yl)amino]methyl]phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxamide (Compound 44) (0.26 g) as pale yellow crystals.
