Procedure

In a mixture of water:ethanol toluene (1:1:10, v/v, 18.0 ml) were dissolved 4-(2-propoxyethoxy)phenyl borate (260 mg) and 7-bromo-1-propyl-N-[4-[[N-methyl-N-(tetrahydro-2H-pyran-4-yl)amino]methyl]phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxamide (396 mg). To the solution was added potassium carbonate (256 mg), and the mixture was stirred under argon atmosphere at room temperature for 30 minutes. To the mixture was added tetrakistriphenylphosphinepalladium (36 mg), and the mixture was heated to reflux under argon atmosphere for 10 hours. The mixture was diluted with ethyl acetate, and washed with water and saturated brine, and the organic layer was dried with anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified with silica gel column chromatography (25 g, ethyl acetate→ethyl acetate ethanol=10:1) and recrystallized from ethyl acetate-IPE to give N-[4-[[N-methyl-N-(tetrahydro-2H-pyran-4-yl)amino]methyl]phenyl]-7-[4-(2-propoxyethoxy)phenyl]-1-propyl-2,3-dihydro-1H-1-benzazepine-4-carboxamide (Compound 26) (252 mg, 53%) as yellow crystals.
