実験手順

(1-Oxo-1H-isoquinolin-2-yl)acetaldehyde (207 mg, 1.1 mmol) was added to a 1,2-dichloroethane solution (4 ml) of 7-(3-aminopropoxy)-1-ethyl-3,3,5-trimethyl-1,5-dihydrobenzo[b][1, 4]diazepine-2,4-dione (329 mg, 1.0 mmol) and sodium triacetoxyhydroborate (381 mg, 1.8 mmol), and stirred at room temperature overnight. Water was added to the reaction mixture, and extraction with ethyl acetate was performed. The organic layer was washed with water, and a saturated sodium chloride aqueous solution, in this order, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (dichloromethane:methanol=20:1). The purified product was concentrated under reduced pressure to thereby obtain 7-(3-{bis-[2-(1-oxo-1H-isoquinolin-2-yl)ethyl]amino}propoxy)-1-ethyl-3,3,5-trimethyl-1,5-dihydrobenzo[b][1,4]diazepine-2,4-dione.
