1-Benzyl-2-oxo-1,2,3,4-tetrahydroquinoline-6-carbaldehyde (0.205 g) was added to a methanol solution (10 ml) of 7-(aminomethyl)-1-ethyl-3,3,5-trimethyl-1H-benzo[b][1,4]diazepine-2,4(3H,5H)-dione (0.213 g). The mixture was stirred at room temperature overnight. Sodium borohydride (0.022 g) was added to the mixture, and the mixture was stirred at room temperature overnight. The liquid was then condensed under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate: methanol=9:1). The purified product was condensed under reduced pressure to give the title compound(0.400 g) as a white amorphous.
