Reaction Steps
1-Ethyl-3,3,5-trimethyl-7-{[N-(2-pyridin-3-ylethyl)amino]methyl}-1,5-dihydrobenzo[b][1,4]diazepine-2,4-dione (0.45 g), 5-bromoquinoline (0.25 g), tris(dibenzylideneacetone)dipalladium (5.4 mg), xantphos (10 mg), and cesium carbonate (0.46 g) were added to toluene (9 ml), and the mixture was heated at 130° C. for 3 days. The reaction liquid was cooled to room temperature. Water was added to the reaction mixture, and stirred for 1 hour, followed by extraction with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate. The filtrate was condensed under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate:methanol=85:15). The purified product was condensed under reduced pressure. A 1N-hydrogen chloride in ethanol solution (1 ml) was added to a ethanol solution (5 ml) of the residue, and the liquid was stirred at room temperature, and concentrated under reduced pressure. Ethanol and ether were added to the residue. The precipitated insoluble matter was separated, washed with ether, and dried to give the title compound (0.20 g) as a yellow amorphous.
