Procedure

In toluene/ethanol/water (=20/1/1, 14.3 ml) was dissolved 7-bromo-1-(2-ethoxyethyl)-N-[4-[N-methyl-N-(tetrahydropyran-4-yl)aminomethyl]phenyl]-2,3-dihydro-1-benzazepine-4-carboxamide (0.32 g). To the solution were added 4-(2-butoxyethoxy)phenyl borate (0.17 g) and potassium carbonate (0.18 g), and the mixture was stirred for 30 minutes under argon atmosphere. To the mixture was added tetrakistriphenylphosphinepalladium (27 mg), and the mixture was heated to reflux for 14 hours. After cooled to room temperature, the reaction solution was added to water, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine and dried with magnesium sulfate. The solvent was removed under reduced pressure, and the resulting residue was purified with silica gel column chromatography (ethyl acetate/ethanol=3/1). The purified residue was dissolved in ethyl acetate, which was filtered to give a solution. The solvent was removed under reduced pressure, which was recrystallized from isopropyl ether/ethyl acetate to give 7-[4-(2-butoxyethoxy)phenyl]-1-(2-ethoxyethyl)-N-[4-[N-methyl-N-(tetrahydropyran-4-yl)aminomethyl]phenyl]-2,3-dihydro-1-benzazepine-4-carboxamide (Compound 90) (15 mg).
